Some friends down at uni asked me to help them for a film quiz one night against loads of other people, and so when I showed up, imagine my delight when the team who had hired me, for whom I was doing a favour, were completely shitfaced on tequila. They'd brought the rest of the bottle, of course, and I had a glass off them gratefully.
Never again.

We (or I) won the quiz, though.
Last night I was on cans of Scrumpy Jack, ran out, then moved onto double vodka and Red Bulls.
