The funniest line I've actually had to use in a "Win it or bin it session"...
Me and two mates had met a couple of girls at a UniBar event about 2 weeks earlier, and had been chatting all night. Ran into them this one night at uni bar again, and I was standing there chatting away to one of them on my own, when one of my mates comes over and tries to steal the conversation (They're pretty bad at this actually). Anyway, he goes to her "You don't even remember who I am do you" and she goes, "yeah, you're X, he's Y" (pointing at my other mate) and then goes, but I can't remember his name pointing at me, while I'm standing there, and my mate goes "Does it matter?" and quicker then a heart beat I chimed in with "f**k oath it does... She'll be screaming it later..."
My mate looked dumbfounded, this chick was like "WTF?..." and then I spent the next 3 hours chatting to her while my mate got no attention...
As I said... It was a win it, or bin it moment...
