I can't believe we don't already have a thread on this.

When I was taking advanced genetics in college, we made up a song for Finals that went something like this:

Let me tell you how it's gonna be
You're gonna give your genes to me
I'm gonna keep them locked up inside
Make some more deoxyribonucleotides!

So, what I envision now, so many many moons later, is something more in the nature of Tom Lehrer's The Elements. It should be to the tune of a Gilbert & Sullivan pattersong, like the Nightmare one if not the Modern Major General, and it can merely list as many sites as they've mapped, or include lyrical lyrics. REM's It's Then End Of The World As We Know It might actually be a[ppropriate, upon further reflection...

Now go forth and multiply!
