When Squad 51 arrives at the former football player's house, his daughter says he "used to play for the Rams". She is referring to the Los Angeles Rams. The Rams football team were founded in Cleveland, Ohio, in 1936, as a member of the original - and short-lived - American Football League. When the AFL folded in 1937, the Rams joined the National Football League, then moved to Los Angeles in 1946. They stayed in Los Angeles until they moved to St. Louis after the 1994 season. Effective for the 2016-17 season they are once again back in Los Angeles.
