"Who's Nuts?" joke
A motorist gets a flat tire and pulls over to the side of the road, where he proceeds to change over to the spare. Whilst removing the wheel, he drops the wheel nuts down the gutter drain. He has a fit and starts shouting obscenities.
Just off the roadway, another guy puts his head to a steel fence and calls out to the motorist, "What's up with you?"
The motorist tells him and the guy behind the fence says, "No problem. Just remove one nut from each of the other wheels and that should get you to the service station at the next town. Just be sure to drive slowly."
The motorist exclaims, "That's a brilliant idea!"
Just then, he notices a sign above the steel grilled fence which reads, "Happy Valley Funny Farm." "How come you can come up with such a great idea," he says to the guy behind the fence, "yet you're in the looney bin?"
To which the inmate replies, "I may be mad, but I'm not stupid!"
What do you call a dog with no back legs and balls of steel? Sparky
