A Fireman is talking to his wife.

I don't remember where I got this joke from, I think the site may have shut down, but here goes.

A fireman is talking to his wife, "Man, everything at the fire station is so structured and organized. When the first bell rings, we go put on all our equipment, when the second bell rings we slide down the poles and get into the fire trucks, and when the third bell rings we go off to put out the fire."

The fire fighter then gets an idea and says to his wife. "From now on, I want that system at home." The wife nods in interest.
"When I come home, I will yell bell 1. You stop what you are doing, and go into the bedroom. When I yell bell 2, you take of all your clothes and lie on the bed. And when I yell bell 3, we have sex all night." His wife excitedly agrees.

The next day, the fire fighter arrives home, he comes through the front door and yells "Bell 1!" The wife stops what she's doing and rushes to the bedroom. As the fire fighter is walking up the stairs he yells "Bell 2!" The wife then takes off all her clothes and lies down on the bed. The fire fighter comes into the bedroom and yells "Bell 3!"

As they are having sex, the wife yells out "Bell 4! Bell 4!"
"What the hell is bell 4?!" The says fire fighter. To which his wife replies "Bring out more hose! You're nowhere near the fire!"
