See, now that just sounds terrifying. I did something similar. Woke the next day witha big cut down my face. I told the kids I was teaching I got it knife fighting.
It's more worrying because other than a very slight graze on my hand I don't have any injuries, my latest theory is that I came over all Elmer Fudd and went hunting wabbits at some point. Perfectly logical from where I'm sitting anyway.
That reminds me of this time when one my high school teachers came in with a broken toe after a holiday and claimed he'd recieved it fighting a shark off; turned out he'd stubbed it on a door frame. Oh how we laughed.
