A teenager tells his father, “There’s water in my car’s carburetor.”

The father looks confused and says, “Water in the carburetor? That’s ridiculous.”

But the son insists, “I’m telling you, there’s water in the carburetor.”

His father is starting to get a little nervous. “You don’t even know what a carburetor is” he says, “I’ll check it out. Where’s the car?”

“In the pool.”
