Quick Answer
Based on the available information, the “slipping on a banana peel” gag has been a staple of comedy films since the early 20th century. The first known appearance of this gag on the big screen was in the Charlie Chaplin movie “By the Sea”, where Chaplin’s character “The Tramp” tosses a banana peel on the ground and then slips on it later. [1][2]
The banana peel gag was soon adopted by other silent film stars like Buster Keaton, who featured it in his 1928 film “The Cameraman”. [3] The gag continued to be used in comedy films throughout the 20th century, including in the 1926 Harold Lloyd film “For Heaven’s Sake”. [4]
However, the available information does not mention any specific 1980s comedy movies that featured the banana peel gag. The gag seems to have been more prevalent in the silent film era and earlier decades of the 20th century. [1][5]
