"In Your Head"

In four-year-old humor anything and everything is rendered hilarious by merely adding the phrase "in your head".

For example:
If I say, "Do you want some breakfast?"
Andrew says, "I want some breakfast in your head!" (Followed by uproarious laughter)

I say, "Go make your beddy-bye."
And he says, "Go make your heady-bye!!" (Uncontrollable giggles)

I say, "It's time to get dressed."
He says, "Okay. I'll get dressed. . .in your head!" (Tears running down his face)

Then I demonstrate my own comedic talent:

When Andrew says, "Can I play with Sammy?"
I say, "You can play with Sammy...
...in your head!"

It goes over really well, cements our friendship forever,
and has lead me to consider a career in preschool stand-up comedy.
