A good example is Spongebob. I used to watch that aaaall the time as a kid.
And in the episode where Spongebob is trying to give Gary a bath, he tries to lure him with like a treasure map sort of deal. Well they get into the bathroom and he takes out some soap and was like "Doubloons! Careful, don't drop them" and winks. THAT WAS TOTALLY A DON'T DROP THE SOAP REFERENCE OMFG.
