The name of this movie comes from M.C. Hammer's 4th studio album "Too Legit to Quit," released in 1991. It is also the name of the title track and first single from that same album, although the spelling of that song is "2 Legit 2 Quit".
Like the real M.C. Hammer, Romany Malco was also a rapper. Around the same time that Hammer was a rap superstar and at the peak of his popularity, Malco went by the stage name R.O.M., and was a member of the rap group College Boyz. Malco and the group were signed to Virgin Records, and released two albums that did moderately well before disbanding in 1994.
