The newly born sperm was receiving instructions in conception from the head sperm.

"As soon as you hear the siren, run for the tunnel and swim in a straight line until you get to the entrance of a damp cavern. At the end of the cavern you will find a red sticky ball, which is the egg. Address it and say, 'I'm a Sperm.' She will answer, 'I'm the Egg.' From that moment on, you will work together to create the embryo. Do you understand?"

The sperm nodded affirmatively and the head sperm wished him luck.

Two days later, the sperm was taking a nap when he heard the siren. He woke up immediately and ran to the tunnel. A multitude of sperm swam behind him. He knew he had to arrive first. When he was near the entrance to the cavern, he looked back and saw he was far ahead. Then he was able to swim at a slower pace until he reached the red sticky ball.

Pfizer Corp. announced today that Viagra will soon be available in liquid form, and will be marketed by Pepsi Cola as a power beverage suitable for use as a mixer. It will now be possible for a man to literally pour himself a stiff one. Obviously we can no longer call this a soft drink, and it gives new meaning to the names of 'cocktails', 'highballs' and just a good old-fashioned 'stiff drink'. Pepsi will market the new concoction by the name of: MOUNT & DO.
