Turn Back!

Once upon a time there was a sperm named George.  All his life George
dreamed of becoming the one sperm to make it all the way to the egg
and become a hero.  George excercised and worked out constantly
preparing for the day....

Then, one fateful evening, George's world began to shake and rumble.
"This is it guys!" he told his weaker sperm friends, "This is it!!"
George moved himself towards the opening and braced himself.
WHOOOSH!!!  George and the others shot off like a rocket.  When the
momentum ceased George swam with everything he had.  Pushing passed
the others, using all his strength to get to the front only to
suddenly stop in horror and turn around swimming back the way he had
come screaming, "Turn back!!  Turn back!!! It's a blow job!!!!......."
