Well, by far one of the most memorable e-tard moment was not my own, but one I am so happy I was part of.
Myself and a few friends were doing our usual weekend club routine, but decided to make the trek to some town in the middle of nowhere that was hosting their first "rave" at an art cafe. My girlfriend spotted some kid from her high school, there all by himself, varsity band letter jacket and dress pants, who kept following us around because he obviously knew nobody there or what the night held for him. He told us how he had never done any drugs, but heard about ecstasy and really wanted to try it, along with the usual fears/weird questions most of us have at the beginning of it all.
We got this kid a tab nobody else there had taken that night, not so much as a joke, but because it was easy/cheap to obtain, and we figured we would make a few bucks off somebody who wouldn't know any better. The kid took it, and we didn't see him for about an hour our so, as we had gone outside to smoke/socialize. We walk back in, and this kid is glued to a strobe light, pupils proper fucked, with a look of sheer amazement and awe for this light. So we were happy he was enjoying himself, but it looked like the usual "Im so fucked right now, all I wanna do is stare at this light for the rest of the night" kind of experience. Ten minutes later the kid is shirtless, sprinting from side to side of this building with the most concentrated look on his face screaming "LOVEEEEE!" at the top of his lungs....this ensued for two hours. No matter how much we told him to down some water, or hang back for a few, he would NOT STOP SPRINTING! After all this stopped, he would not stop running everywhere he went, he would run in place when he talked to people, and he ended up being a sort of makeshift dj-go for guy at some point.
Needless to say...he is now known as "The Runner"
