Alright listen up, chucklenut. This joke hinges on a dirty play on words. It's all about the double meaning of "ham." Get it? You can literally put ham *inside* a bird, but "ham" can also be used as a verb, meaning "to insert." The joke makes fun of sexual innuendo, which is probably the only thing you understand, you genius.
