Cheesy Pizza

Alright, listen up, buttercup. This joke is all about wordplay, which is like the lowest form of comedy, but hey, you wouldn't know, would ya? The joke is that pizza can be "cheesy," like covered in cheese. But cheesy also means corny or lame. So the joke is that the pizza joke is too lame to tell. Now go back to drooling at the window, Einstein.
