Problem: Nightcrawler (Kurt Wagner) is a fictional superhero appearing in American comic books published by Marvel Comics, commonly in association with the X-Men. Created by writer Len Wein and artist Dave Cockrum, he debuted in the comic book Giant-Size X-Men #1 (May 1975). Nightcrawler is a member of a fictional subspecies of humanity known as mutants, who are born with superhuman abilities. Nightcrawler possesses superhuman agility, the ability to teleport, and adhesive hands and feet.

For a time, Kitty Pryde and Nightcrawler express some resentment over the X-Men's failing to contact them after their supposed deaths. Following the wedding of Captain Britain and Meggan, Excalibur disbands and Nightcrawler returns to the X-Men with Shadowcat and Colossus. Yet, as soon as they return, they face a group of impostors following Cerebro, in the guise of Professor X. Wanting to devote more time to priesthood, Nightcrawler shares team leadership with Archangel. However, his work as a priest is retconned to be an illusion; he had, in fact, never attained priesthood. He has also met his half-brothers Nils Styger, alias Abyss, and Kiwi Black. With them, Nightcrawler defeated his father Azazel, who had tried to use him as a pawn in escaping his prison. Later, Nightcrawler served as the new leader of the Uncanny X-Men team alongside Wolverine, Bishop, Psylocke, Cannonball, and Marvel Girl. In the last mission against the Foursaken, Nightcrawler took Marvel Girl, Psylocke, Bishop, and Cannonball to Central Park. He later helped Storm liberate Africa from her uncle's control. Afterwards, Professor X recruited him, along with Darwin, Havok, Marvel Girl, Warpath, and Polaris, to participate in a space mission to stop Vulcan from laying waste to the Shi'ar empire. During the battle with Vulcan, Nightcrawler helps get the injured Professor X and Darwin back to their spaceship. While there, trying to save Professor X, Lilandra sent the ship on its way back to Earth, leaving half the team behind. Kurt is still part of Professor X's team, helping Charles find Magneto before the government does, while the rest of the team search for the Morlocks.

Problem: Santana is a Latin music and rock band formed in San Francisco, California in 1966 by Mexican-American guitarist Carlos Santana. The band came to public attention with their performance of "Soul Sacrifice" at Woodstock in 1969. This exposure helped propel their first album, also named Santana, into a hit, followed in the next two years by Abraxas and Santana III. Lineup changes were common.

The follow-up to Supernatural came three years later and was highly anticipated by international media and fans alike. On October 22, 2002, Shaman was released worldwide. Although it initially sold briskly (298,973 copies in the US in its first week) and debuted at number 1 on the Billboard 200, the album's appeal quickly wore off and it soon slid down the charts. Despite this, it went on to sell 2x platinum in the US, and achieved platinum status in several other countries including Australia. The first single released from the album, "The Game of Love", which featured vocals from Michelle Branch, debuted at number 5 on the Hot 100. The album's next four singles failed to chart in most countries, but the final single, "Why Don't You & I", featuring the vocals of Alex Band, reached number 8 on the Hot 100. Musically, the album was a return to a more conventional sound for the group, with a mainly Latin rock-based sound. With their renewed appeal worn off, another three-year wait saw the release of 2005's All That I Am. The album debuted at number 2 on the Billboard 200 but fared worse internationally, and quickly lost appeal. The album, a continuation of the Latin-rock influenced sound of Shaman, achieved gold certification in the US. A five-year break from recording saw the release of another studio album, 2010's Guitar Heaven. Musically it was a drastic change for the band, with a far heavier sound at its core and strong heavy metal influences. It debuted at number 5 on the Billboard 200 but marked another decline for the band, failing to achieve gold status. In 2012 the group released Shape Shifter, which returned to the conventional Latin rock sound and was completely album-oriented, as no singles were released from it. It debuted at number 16 on the Billboard 200.

Problem: Norman Percevel Rockwell (February 3, 1894 - November 8, 1978) was a 20th-century American author, painter and illustrator. His works have a broad popular appeal in the United States for their reflection of American culture. Rockwell is most famous for the cover illustrations of everyday life he created for The Saturday Evening Post magazine over nearly five decades. Among the best-known of Rockwell's works are the Willie Gillis series, Rosie the Riveter, The Problem

Rockwell's family moved to New Rochelle, New York, when Norman was 21 years old. They shared a studio with the cartoonist Clyde Forsythe, who worked for The Saturday Evening Post. With Forsythe's help, Rockwell submitted his first successful cover painting to the Post in 1916, Mother's Day Off (published on May 20). He followed that success with Circus Barker and Strongman (published on June 3), Gramps at the Plate (August 5), Redhead Loves Hatty Perkins (September 16), People in a Theatre Balcony (October 14), and Man Playing Santa (December 9). Rockwell was published eight times on the Post cover within the first year. Ultimately, Rockwell published 323 original covers for The Saturday Evening Post over 47 years. His Sharp Harmony appeared on the cover of the issue dated September 26, 1936; it depicts a barber and three clients, enjoying an a cappella song. The image was adopted by SPEBSQSA in its promotion of the art. Rockwell's success on the cover of the Post led to covers for other magazines of the day, most notably the Literary Digest, the Country Gentleman, Leslie's Weekly, Judge, Peoples Popular Monthly and Life magazine. When Rockwell's tenure began with The Saturday Evening Post in 1916, he left his salaried position at Boys' Life, but continued to include scouts in Post cover images and the monthly magazine of the American Red Cross. He resumed work with the Boy Scouts of America in 1926 with production of his first of fifty-one original illustrations for the official Boy Scouts of America annual calendar, which still may be seen in the Norman Rockwell Art Gallery at the National Scouting Museum in the city of Irving near Dallas, Texas. During World War I, he tried to enlist into the U.S. Navy but was refused entry because, at 140 pounds (64 kg), he was eight pounds underweight for someone 6 feet (1.8 m) tall. To compensate, he spent one night gorging himself on bananas, liquids and doughnuts, and weighed enough to enlist the next day. He was given the role of a military artist, however, and did not see any action during his tour of duty.
