When I was a kid I learned from other kids on the block about making prank phone calls. This is before caller ID and you just dialed a number at random. There are a few standard ones like “excuse me but is your refrigerator running? Then catch it!” Another one that I didn’t understand as a kid was “Do you have Prince Albert in a can? Then let him out!” It makes so much sense if you know that it is a type of tobacco.
