Going up?

Welcome to the final day of watermelon jokes! The boy is out of school tomorrow for a teacher inservice. He has requested a joke in his lunch even though he won't be going to school. I'm going to try to think of something special since he'll be eating at home. It might have something to do with jokes I can't send to school, but he thinks are hilarious. Perhaps something about butts...

But I'm getting ahead of myself. Here's today's doodle!

Happy day-before-Friday!
