Thinking about it now, seeing as I've mentioned it on one of the other threads, the worst embarrising moment for me was on a field trip with some Year 7 pupils to a nature reserve where we stayed for a couple of nights.
Me and a couple of friends were there as helpers to the teachers but on the first night of staying a bunch of the kids were in the same cabin as us so we're all sat round the table whilst there writing all their notes when one of my friends turns round.
Friend 1: Want a beer?
Friend 2: You brought some?
Me: What? We can't have them with this lot around!
friend 2: Sure we can, They won't mind, do you kids?
Kids: No! Mind what?
Friend 1: See perfectly innocent.
Me: Okay, maybe 1
*ten beers later*
Friend 1: I thought we were only having one?
Me: Don't be daft, one's never enough.
Friend 2: I'm off to bed, I don't feel to good.
*Friend 2 disappears to the bedrooms, shortly followed by friend 1, niether seen till morning*
Kids (somehow still awake): Tell us a story, go on.
Me: I don't know any.
Kids: Sure you do, something romantic or scary.
Me: Romantic hey? Well let's see, maybe I could tell you what me and my girlfriend get upto.
Kids: Your girlfriend?
Me: Didn't you know, I'm so totally dyke like!
*As you can tell, i was definately drunk*
Kids: What's it like then?
Me: well.....
*Next hour spent describing sex life in huge detail*
Kids: Woah. Amazing.
Me: what's amazing. Get to bed you scallywags!
Kids: yes Marie.
*Kids stumble off, I wake up next morning with hangover, on the settee in the room we had all been talking in, wearing nothing but panties whilst spotted by the Headmistress!*
Me: Morning, ma'am, whatsup?
Headmistress: your a disgrace, look at you!
Me: huh? What?
Headmistress: drunk as a skuck, telling strange stories to the girls, filling there heads with strange fantasies. get off my trip at once, you here me. Don't think your coming again either.
Me: Okay, i'll go.
*Start heading towards the door*
Headmistress: Put some clothes on first woman!
Now you can understand how embarressing that was, especially since my story spread like wildfire between the year 7's. I think that really does count as a drunken Nyamo moment!
