SOMEONE knew I needed a laugh

This is what a five year old boy will draw on the board while waiting for his bus to be called.

Any ideas on what it REALLY is?

I'll post the answer tomorrow morning in the comments. The winner will receive a standing ovation by anyone who is my house at the time, and two loud barking dogs who are fully potty trained. Except perhaps the one who's epileptic, and occasionally pees all over the floor if his mother, sister and brother ALL decide to give him his morning pill. (s) He is, however, EXTREMELY friendly and loves to go on field trips.
