i think a number 3 is unrecognisable..especially when you have a massive hangover...a nice mix...pray it dont happen at work!!!!! my sis had one recently at an open air concert and closed down the portaloo!! claim to faim eh?...go sis!!
I always thought is was to do with the hole it came out of rather than what came out. #3 would then be oral, leaving me now to wonder what #4 would be?
