A longer version of somok's joke that my highschool's senior class printed on the backs of our t-shirts for homecoming is this:

 Σ ∫ex= f(un) ∴ yo
u→xc
which reads:

As u approaches x to the c power, the indefinite integral of e to the x is equal to the function u sub n, therefore: y sub zero (or y naught)

OR:

As you approach ecstacy, sex is fun, so why not?

There were a lot of geeks in my senior class, yes, and no, we didn't get in trouble for the shirts. The only teacher who worked out what it said was a horny old bastard who thought the shirts were fantastic.

I HAVE BEEN TOLD THAT THIS IS NOT EASILY VIEWABLE ON SOME INTERNET BROWSERS. I WILL FIX IT AS SOON AS I CAN FIGURE OUT HOW.
