Problem: Bruce Randall Hornsby (born November 23, 1954) is an American singer and pianist. Hornsby draws frequently from classical, jazz, bluegrass, folk, Motown, gospel, rock, blues, and jam band musical traditions. Hornsby's recordings have been recognized on a number of occasions with industry awards, including the 1987 Grammy Award for Best New Artist with Bruce Hornsby and the Range, the 1990 Grammy Award for Best Bluegrass Album, and the 1994 Grammy Award for Best Pop Instrumental Performance. Hornsby has also achieved recognition for his solo albums and performances, his touring band Bruce Hornsby and the Noisemakers, his bluegrass project with Ricky Skaggs and his appearances as a session and guest musician.

Hornsby played more than 100 shows with the Grateful Dead from 1988 until Jerry Garcia's death in 1995. At some shows in 1988 and 1989, he joined the band as a special guest and played accordion or synthesizer. Starting in the fall of 1990, he played piano (and frequently accordion) at many gigs following the death of longtime Grateful Dead keyboardist Brent Mydland, who died suddenly in July 1990. Mydland's place was filled in September 1990 by Vince Welnick, who became the sole keyboardist by March 1992, although Hornsby still sat in with the band on occasion. Hornsby's own music evolved significantly during this time period. Critics have suggested that the Dead's vibrant tradition of melding folk music and the blues with psychedelic rock in "loose-knit expressions" and extended jamming "further pushed [Hornsby] outside the confines of mainstream pop." Critics have also commented upon the "close musical connection" formed between Hornsby and Jerry Garcia, suggesting that Hornsby's particular style of jazz-fueled improvisation added to the band's repertoire, and helped to revitalize and refocus Jerry Garcia's guitar solos in the band's sound. Hornsby's friendship with Garcia continued, both inside and outside the band, as the two "challenged" each other to expand their musicianship through several other album and live collaborations. Above all, Hornsby's musical versatility and ability to slip in and out of extended freeform jams won over longtime Grateful Dead fans. Since his first involvement with the Grateful Dead, Hornsby's live shows have drawn Deadheads and Hornsby has commented: "I've always liked the group of fans that we've drawn from the Grateful Dead time, because those fans are often adventurous music listeners." He has performed a number of their songs at his concerts and as homages on studio and live albums, while Hornsby originals "The Valley Road," and "Stander on the Mountain," appeared several times in the Dead's setlists. Hornsby also co-performed the improvisation "Silver Apples of the Moon" for the Grateful Dead's Infrared Roses. Hornsby was the presenter when the Grateful Dead were inducted into the Rock and Roll Hall of Fame in 1994 and in 2005 he participated in "Comes a Time", a tribute concert to Jerry Garcia. He continues to work with Dead-related projects, such as Bob Weir's Ratdog, Mickey Hart's solo projects. He performed as part of The Other Ones in 1998 and 2000, and on occasion sat in with The Dead. Hornsby continues to be involved in the Grateful Dead and Furthur community, having opened All Good Music Festival in 2012 featured with Bob Weir on rhythm guitar. In mid-2013, Hornsby performed with Grateful Dead-influenced bluegrass group Railroad Earth. Hornsby reunited with surviving members of the Grateful Dead along with Trey Anastasio from Phish and Jeff Chimenti at Levi's Stadium in Santa Clara, California, and later at Soldier Field in Chicago, Illinois, in July 2015.

Problem: Stephen McDannell Hillenburg (born August 21, 1961) is an American cartoonist, animator, writer, producer, director, and former marine biologist. He is the creator of the Nickelodeon television series SpongeBob SquarePants (1999-present) which he has also directed, produced, and written. It has gone on to become one of the longest-running American television series as well as the highest-rated show ever to air on Nickelodeon. Born in Lawton, Oklahoma and raised in Anaheim, California, Hillenburg became fascinated with the ocean as a child and also developed an interest in art.

Hillenburg's wife, Karen, is a chef who teaches at the New School of Cooking in Culver City, California. Hillenburg deems her to be the funniest person that he knows. The couple have a son named Clay (born c. 1998). Hillenburg formerly resided in Hollywood and in Pasadena, and now lives with his family in San Marino, California. His hobbies include surfing, snorkeling, scuba diving, and performing "noisy rock music" on his guitar. He would jam with his son who is a drummer which, according to Hillenburg, is "a great way to bond with each other." He also enjoys birdwatching at home, but says that he was always "an ocean freak". According to his colleagues, Hillenburg is "a perfectionist workaholic". He is also known for his private nature. Julia Pistor, co-producer of The SpongeBob SquarePants Movie, noted that Hillenburg is "very shy". She went on to say, "He doesn't want people to know about his life or family. He's just a really funny, down-to-earth guy with a dry sense of humor who puts his family first and keeps us on our toes in keeping our corporate integrity." Hillenburg said about himself, "I make animation because I like to draw and create things. I have no real interest to be on camera or to be a celebrity. It's not that I don't like people, but I like having my privacy." In March 2017, Hillenburg disclosed that he was diagnosed with amyotrophic lateral sclerosis (ALS), a terminal illness that affects and causes the death of neurons that control the brain and the spinal cord. He released a statement to the Variety magazine after his diagnosis, in which he affirmed that he would continue to work on SpongeBob SquarePants "for as long as [he is] able." He stated further, "My family and I are grateful for the outpouring of love and support. We ask that our sincere request for privacy be honored during this time." Hillenburg is currently in the early stages of the disease, according to a source close to him.
