My 3 year old likes to tell "apple jokes". Usually they go something like this: "Why did the monster eat the apple?" "Because it was hungry!" [uproarious laughter] or "How did the apple get in the monster?" "The monster ate it!" [snort snort giggle giggle]. But she actually told one the other day that made me laugh.
3 year old: "Apple!" (long pause)
Me: "Oh, is that an apple joke?"
3 year old: "No, it's a apple and peanut butter joke, only without the peanut butter!"
Yeah, and I used to have a shirt like that, only it was a different color and mine were pants.
