Heh!A chummer and I once crashed a university lecture on Forensic Entomology cause we had nothing else better to do for a few hours... Much to the chagrin of most of the folks around me, I brought a plastic bowl of leftover pasta and tomato sauce to munch on while watching time last footage of various bugs breaking down a cadaver...
We giggled through the whole thing!
I'm glad I wasn't sitting near us, trying to take notes to pass a test on the subject or anything...
