When Pee-wee ate or tasted something, typically during Snack Time, he often exclaimed enjoyment by saying, "Mmm, (object)-y!". For example, he would say "Mmm, lemony!" when tasting something with a lemon flavor. This gag was later used on The Simpsons by Homer and by Johnny Bravo in the Cartoon Network cartoon of the same name. An example of the joke being used during other situations was an innuendo, where Pee-wee was describing the bust that Dirty Dog made for Miss Yvonne in the episode Playhouse in Outer Space; he said "Mmmm, busty!" and laughed.
