The fireman and his wife!

A fireman comes home from work one day and tells his wife,
"you know we have a wonderful system at the fire station; bell 1 rings and we put on our jackets
bell 2 rings and we all slide down the pole
bell 3 rings and we're on the fire truck ready to go.

from now on when i say bell 1 i want you to strip naked
when i say bell 2, i want you to jump into bed
and when i say bell 3 we're going to make love all night."

the next night he comes home from work and yells bell 1!
his wife promptly takes all her clothes off
then he yells bell 2! his wife jumps into bed
when he yells bell 3! they begin making love, after a few minutes his wife yells bell 4!

what the hell is bell 4? asks the fella

roll out more hose, she yells, your nowhere near the damn fire!
