so my friends and i were celebrating the end of school for the year by going to see a movie - i think it was transformers 3, but i could be wrong. either way, we had a good few hours before the movie started, so we decided to go to the pizza place next door beforehand to eat dinner.

this pizza place is one of those italian restaurants that kind of serves two roles. the front is a pretty standard pizza parlor, with the usual selections and some tables to sit at if you want to just quickly eat a slice. the back of the place is a fancier, full service restaurant. i was in a large enough group that they had to seat us back there. they handed out menus, which we all looked at even though we were almost certainly getting pizza. while reading, i notice "antipasto" as a section, and i find it funny how much it looks like "anti-pasta". so, in my typical attention-whore manner, i decide to make the whole table laugh when the waiter gets there.

so he starts taking our orders, and when he gets to me i say:

"i just have a question about this 'anti-pasta' - is it okay if it touches normal pasta, or will it blow up?"

my friends erupt in laughter, which is a good sign. but the waiter looks pissed off.

"what, you mean like antimatter and matter? you know, i'm a physics major, so i understand that."

unbeknownst to me, he was studying physics at the local university and waiting tables as a side job. he took my joke as an insult that was supposed to go over his head because waiters are stupid, and i felt like a tremendous asshat.
