A fireman comes home from work one day and tells his wife, “We have a wonderful system at the fire station:
Bell 1 rings, we put on our jackets;
Bell 2 rings, we slide down the pole;
Bell 3 rings, we’re on the trucks.
From now on, we’re going to run this house the same way. When I say Bell 1, I want you to strip naked. When I say Bell 2, I want you to jump into bed. When I say Bell 3, we’re going to make passionate love.”
The next night, the fireman comes home from work and yells,
“Bell 1!” His wife takes off her clothes.
“Bell 2,” and his wife jumps into bed.
“Bell 3,” and they began to make love. After two minutes, his wife yells,
“What’s Bell 4?” the husband asks.
“Bring out more hose!,” she replies, “you’re nowhere near the fire!”
