Don't Go There

So this caretaker is at home one night when he suddenly hears screaming coming
from one of the apartments (flats).  Running through the entire block, he finally 
finds a woman about to give birth.

"Help me!" she cries "It's coming out!"

The poor guy is stunned and asks what he should do.

"When you see the head, pull it out!" the woman moans.

The guy sees the head and pulls out a baby boy.  "Now what?" he says.

"Grab it by the ankles and spank it!" the woman yells.

So the guy grabs the baby by the ankles and starts wailing the tar out of it, 
yelling, "And don't you *ever* go in there again!"
