What do boobs and toys have in common?
Kids end up playing with toys, but adults end up playing with boobs.
Listen up, buttercup! This "joke" is saying that both kids and adults like playing with stuff. Kids play with toys and adults play with boobs. It's not rocket science, but you probably think it is. Just like you think washing your feet is a personality trait.
