A jocular grocery sign was in the comic strip Frank and Ernest:
“Produce Dept. Notice! Take lettuce from top of stack, or heads will roll!”
The Frank and Ernest comic strip joke was cited in a newsgroup in December 1999, but it’s uncertain when the strip was first printed. The comic strip was republished in July 5, 2007.
