I was looking for a picture of the Batman cape and mask the kid I saw was wearing and I found this. I think it is pretty funny. I hope you do too.
When I was a little kid, probably your age, I once put feet pajamas on our dog Dizzy. Dogs shouldn't really wear pajamas. You want to know why. Because Dizzy went outside to pee and he peed all over the pajama bottoms. They were my pajamas. Aunt Jen thought it was the funniest thing ever.
