[Semper Paratus]

Now, why would nature evolve the male sperm to run interference for itself and seek to destroy competing sperm?

I remember the Woody Allen movie where he played a sperm dressed as airborne about to jump worrying about what's out there:

"I heard you hit this rubber barrier and are poisoned."
"Or even worse, what if its a homosexual encounter?"

[Political Junkie Too]

That was "Everything you wanted to know about sex, but were afraid to ask." My favorite line from the scene: "What if he's an astronaut? I might wind up on the ceiling!"
