I once got literally stuck behind a set of decks while tripping me nut off on acid for about 4 hours... someone had move the speaker so it trapped me in, and I just couldn't figure out how to get out... had a continuous routine going on of mix, stand back flat against the wall with arms out letting out a big sigh of relief, observe the carnage going on in the room for a bit, realise I didn't want to be stuck in the dj booth anymore and wanted someone else to take over... start looking round me for a way out, fail to find a way out, start looking at the record spinning, forget why I was looking at the record spinning, get the feeling I was meant to be doing something about the record spinning things, pull myself together enough to realise I needed to find another one of them records to put on the other spinny thing or something... look in my bag, pull records out randomly, find one with good colours on it, forget what I was doing, stand up, realise I was behind the decks and therefore must be djing... somehow manage to concentrate reeeeeealy hard for long enough to mix... stand back flat against the wall with arms out letting out a big sigh of relief and repeat for 4 hours.
didn't really help my sanity that everyone else had necked acid as well, and were all playing along manicly on bass guitar (2 people at once onthe same guitar), another pair on xylophone, 3 on bongos, someone on spoons, and someone periodicly mcing via some headphones through the bass guitar amp (coz I kept unplugging him from the dj mixer).
later got a text from the lass I'd originally taken the acid with asking where I'd dissapeared to coz apprently I'd just left her in a different room or something... she didn't think much of my excuse of not being able to work out how to escape from the decks
