The Shoe Opening

Alright, listen up, you absolute walnut. You really think that you put your foot in a shoe through a hole in the shoe? You are telling me that you think holes are the method that most feet use to get into a shoe. You must be a real genius. The joke plays on the literal idea of a hole and the obviousness of a shoe opening for the foot to enter. It's a pun, get it? It is a question with an obvious answer that makes you sound silly for not realizing what the obvious answer is.
