Problem: John F. Maulbetsch (June 20, 1890 - September 14, 1950) was an All-American football halfback at Adrian College in 1911 and for the University of Michigan Wolverines from 1914 to 1916. He is also a member of the College Football Hall of Fame. After playing with an independent football team in Ann Arbor and at Adrian College, Maulbetsch became one of the most famous American football players in 1914 while playing for the University of Michigan. Maulbetsch became known as the "Human Bullet" because of his unusual low, line-plunging style of play, and was also known as the "Featherweight Fullback" because of his light weight and small size.

Much of the attention on Maulbetsch focused on his diminutive size and unique running style. At 5 ft 7 in (1.70 m), and 155 lb (70 kg), Maulbetsch was a small back, even by the standards of his day. And his running style saw him bend his torso and propel himself like a projectile into the opposing line. Indeed, he won several nicknames based on his size, running style, and fighting spirit, including the "Human Bullet," "Mauly", the "Human Shrapnel", the "Featherweight Fullback", the "Michigan Cannon Ball," and the "German bullet." Comparisons of Maulbetsch to military armaments were common. In addition to the "bullet", "shrapnel", and "cannonball" nicknames, the Syracuse Herald observed: "Standing up in front of a Krupp gun has its dangers, but it is not to be compared with the dangers of standing in front of Maulbetsch when he is going full speed ahead." Maulbetsch's style was described as "line-plunging." A New York newspaper noted: "When the ball is snapped to him he almost doubles himself up, and, with his head aimed at the knees of the opposing line, he dives head first. Those who have seen Maulbetsch in action marvel at the great momentum he can get up in two or three steps." Noted football writer Walter Eckersall said: "Mauly is a little fellow, being built close to the ground. They say that when he plunges at the line his head is almost on a level with his shoe tops - that he hits so low that it's well nigh impossible to stop him." An Iowa newspaper wondered how it was possible "for a man to smash into a line of human bodies with the force that Maulbetsch does and come out of the game without a broken neck." Maulbetsch was said to run "so low that he could dash under an ordinary table without losing his feet." At a coaching conference in the 1920s, a coach doubted the table-ducking story and challenged Maulbetsch. The doubter later recalled: "I began ribbing him about this table-ducking stuff and finally offered to bet him he couldn't do it. Well, we got a table up in a room, Johnny tucked a water pitcher under his arm and backed against the wall. Darned if he didn't do it, the only thing, that water pitcher broke in a million pieces." Asked about the incident, Maulbetsch said it was true, except one part. Maulbetsch insisted there wasn't a nick on the pitcher.

Problem: Testament is an American thrash metal band from Berkeley, California. Formed in 1983 under the name Legacy, the band's current lineup comprises guitarists Eric Peterson and Alex Skolnick, lead vocalist Chuck Billy, drummer Gene Hoglan, and bassist Steve Di Giorgio. Since its inception, Testament has had numerous lineup changes, leaving Peterson as the only constant member. Billy replaced original singer Steve "Zetro" Souza (who left the band to join Exodus as the replacement of Paul Baloff) in 1986, prior to the recording of their first studio album, The Legacy, and has been a member of the band since.

As early as 2009, Testament commenced writing new material for their tenth album. In an interview with Metalheadz, guitarist Eric Peterson stated that there were about four songs written and that "there's other guys in the band who like to play the more rock melodic style but the next one is gonna be a bit heavier." In a January 2011 interview during the 70000 Tons of Metal cruise, frontman Chuck Billy revealed that Testament had been working on six new songs, with four or five "maybe left to write," and would begin recording their new album by early March. On 18 May 2011, guitarist Alex Skolnick posted an update on his Twitter, saying, "Another tune done! My riffs from last week [plus] some of [fellow Testament guitarist Eric Peterson's plus] new ones we wrote today. Planning one more, then we've got more than we need." Testament began recording their tenth studio album on June 20, 2011. Drummer Paul Bostaph was unable to take part in the recording due to a "serious injury", although he was expected to rejoin when the band tours to support the album. Gene Hoglan, who played drums on the band's 1997 album Demonic, filled in for Bostaph. It was also reported that Lamb of God drummer Chris Adler would make a special guest appearance on a couple of bonus tracks. Testament appeared at the California dates of the summer 2011 Rockstar Energy Drink Mayhem Festival, replacing In Flames. On 14 July 2011, it was announced that the tenth Testament studio album would be called Dark Roots of Earth, which, after many delays, was released on July 27, 2012. Dark Roots of Earth debuted at No. 12 on Billboard 200, the band's highest chart position to date. Prior to the album's release, the band toured in the fall of 2011 with Anthrax and Death Angel. Overkill was invited to the tour, but due to the pre-production of their sixteenth studio album The Electric Age, they did not participate. It was announced on 1 December 2011 that Paul Bostaph had left Testament. Gene Hoglan recorded the drum tracks for Dark Roots of Earth and continues to play live with the band. In interviews, Testament have expressed pleasure in Hoglan's playing, and hope that he would continue playing with the band for the foreseeable future.
