The Best Way to Carve Wood

Alright, listen up, chucklehead. You're the kind of person who probably thinks wood comes from the grocery store. This joke is a pun, which means it uses a word that sounds like another word for a funny effect. In this case, "whittle" (carving wood bit by bit) sounds like "little," so the answer is just saying to carve it "little by little". Get it now, Einstein?
