I know my kids are not the only ones obsessed with the Nintendo's little overalled hero, so here's the latest Mario joke to come home from the playground. Since I've heard it repeated 10,000 times already and can't remove its presence from my head, I thought I might as well share:

"Knock knock."

"Who's there?"

"Yah Wah."

"Yah Wah who?"

"I didn't know you were Mario!" (That's your cue to fall down giggling until you can't breathe then get up and tell the joke again. Repeat until you fall asleep tonight. Wake up and start again first thing tomorrow.)

And yah wahoo! It's a holiday here in the U.S. tomorrow. Happy Independence Day to all. Enjoy the joke and the fireworks!
