Well, they're three-day festivals, full of bands, music, booze, food and party. Better yet, last August I was at Sziget, a 7-day, 24-hr party on an island in Budapest. It was awesome. But yeah…sometimes you get a bit drunk, and you party a bit too hard, and then the sunglasses pay for it. I've actually lost three or four pairs in total to these festivals.
But my own glasses have never been harmed. Basically because I always wear them, so I always keep an eye on 'em.
As for topic:
I often get called Giel Beelen, after a Dutch radiohost:
Me:

Him:

It's not a cartoon, but people keep calling me Giel when I'm walking down the streets.
It's funny.
