The gag comes from Beverly Hills Cop, the 1984 action comedy starring Eddie Murphy as Detroit detective Axel Foley. In Los Angeles, Foley stuffs a banana into the tailpipe of a police car tailing him, stalling it so he can slip away. The scene became one of the film's most quoted moments and turned the phrase into shorthand for low tech sabotage. Clips and references still circulate in car memes, prank videos and movie quote collections because the trick is visual, simple and instantly understood.
