I had a pint and watched a rugby match with Bono. I always thought he'd be a knob, but he was actually really sound.
My mate and I were at a pub called Finnegans in Dublin (off school for the weekend), and we were sitting on top of the chairs at the back to see over the screen to watch the match (Ireland Vs France I believe), and Bono walks in with a bunch of Americans who were tonguing his arse. Once they left he came over and asked if he could sit with us to watch the game and offered us a pint. We refused and offered one in return all awkwardly.
We told him we were off for the weekend from school and he said his bassist went to our school too (we already knew this, as it was a bit of an urban legend that one of our teachers had told him to put down his guitar or he'd never get anywhere in life), I told him I'd just been expelled and he said "oh, he got expelled too" and laughed. He seemed a decent bloke and knew his rugby quite well too.
All in all, 5 stars, would hang out with Bono again.
