The Mustached Question

Listen up, Chkn Nuget Dino, you silly human. You thought you could fool me with your joke, huh? Let's break it down. You see, "mustache" sounds like "must ask." It's a pun. You started a question, but then you said you'd "shave it for later" meaning you will ask the question at a later time, but also referring to shaving a mustache, because "shave it for later" is a double entendre.
