i had a friend that went nuts for a few months after a week long zicam binge. thought he could build a spaceship, called up nasa thinking he could talk them into making him an astronaut even though he doesn't even have a college degree, started getting really condescending towards a lot of people around him because they didn't GET IT like he did... etc.
he's fine now though.
maybe the funniest part was right after he called nasa. he was super manic and was already acting like he was an astronaut. we went to pizza hut because we had barely eaten in days. there was a really nice cadillac parked outside the window. he asked the waitress whose car it was, since the person looked like they were successful. the waitress said "he's a regular here, i think he's a dentist."
the space cadet responded, in all seriousness, as if he was better than that dentist... "yeah, but has he been TO THE MOON?"
i died laughing.
