Here are mine:
"It's not like a cake where the more raisins the better." -Martin Osborne
"I feel safer rock climbing than programming in C++." -Martin Osborne
"Ada is to intelligent design as C++ is to evolution." -Michael Meehan

"Doesn't every orgasm have the potential to be an apocalyptic orgasm?"
(Andrea Gogrof-Voorhees)
