bikers fairground
Several years ago I went with some friends to a bike show / trade fair thing in edinburgh. The best thing there was a show put on by The Purple Helmets Display Team. It was basically a clown / acrobatic show on mopeds with a fairly funny commentator throwing double-entendres in wherever if could and hamming up the "death defying, high speed stunts"

If you ever have the opportunity I would thoroughly recommend. I tried looking them up on t'internet once but gave up after considerable time wading through the inevitable sea of bumbandit pornery.

They do have a website, I've seen it.
Not as funny as their act though. The commentator said 'While you may have noticed that none of our riders is actually wearing a purple-coloured helmet today, I can assure you all that each and every one of them does indeed possess a purple helmet of his very own.'

They perform at the TT every year too.

True story
4 of them drove past me yesterday while I was outside work having a smoke! I do live on the Isle of Man and it is TT week, so you kind of get used to seeing that kind of thing!
