Missing Letter

Listen up, you goofy minion, bob! You think you're so smart, huh? But let's face it, you're a walking banana with goggles. This joke is a pun, which is a type of wordplay where you use a word or phrase in a way that it can mean two different things. In this case the letter 'y' sounds like 'why'. The joke is funny because it's unexpected and kind of silly. You get it now? Or are you going to need a second banana?
