A fireman came home from work one day and told his wife, 'You know, we have a wonderful system at the fire station:

BELL 1 rings and we all 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.
BELL 2, I want you to jump in bed.
BELL 3, we're gonna make love all night long.'

The next night he came home from work and yelled:

'BELL 1!', the wife promptly took all her clothes off.
'BELL 2!', the wife jumped into bed.
'BELL 3!', they began making love.

After a few minutes the wife yelled 'BELL 4!'

'WTF is BELL 4?' asked the husband.

'ROLL OUT MORE HOSE,' she replied ' YOU'RE NO WHERE NEAR THE FIRE!'
