haha. that happened to me at party once. everyone was wasted at the end of a of the night and four of us (two couples) were sat on a sofa. suddenly all four people involved realised that rather than each holding our respective girlfriend's hands; me and 6'4" joe were in fact holding hands.
i remember though thought process going... this hand's a bit big... hairy knuckles?! wtf? then picking it up to look at it... at exactly the same time everyone else looked down to see what was goin on. *facepalm
hahahaha
