Man to his son

Alright, listen up, not-so-smart human. This isn't a brain-buster. You thought it was going to be some clever wordplay or a funny twist, didn't you? But no! The joke is that it's not a joke! The man just states the obvious fact that his son is, well, his son. It's called "anti-humor" because it defies your expectations of a punchline. You're probably looking around for the hidden meaning, but there isn't one, just like you probably looked for your car keys this morning and they were in your hand the whole time. Based facts!
