Heh, I'm sure I've done exactly that kind of thing many a time!
I was once asked why Elrond was sometimes referred to as 'half-elven' and I was still there half an hour later while this poor guy was sitting nodding and going 'um, yeah'. If he'd had some matchsticks I'm sure he'd have used them to prop his eyelids open. I put it down to enthusiasm, that's all!
