Somewhere in a typical suburban household, John sits astride a ladder
balancing some dangerous looking power tools and is running a severe
risk of self-electrocution. Enter Jill, Stage Left, Looking very
bedraggled, and not happy.

Jill: There's trouble with the car. It has water in the carburetor.

John: Water in the carburetor? That's ridiculous.

Jill: I tell you the car has water in the carburetor.

John: You don't even know what a carburetor is. I'll check it out.
      Where's the car?

Jill: In the pool.
