I sometimes share clean adult jokes that are too clever for a 2 year old to grasp. Sometimes it is fun to see the confused look on his face when he sees me cracking up on my own jokes. Yes, I laugh at my own jokes, moving on.
We're hanging out at a coffee shop and I start with the setup for a great joke.
Me: Vian, did you know that humans eat more bananas than monkeys?
Vian: What? They eat monkeys?
Me: LOL!! Way to ruin the punchline man.
