A motorcycle display team who specialise in riding displays performed without clothing. Many of the displays have humourous edge (farting through a trumpet or balancing spinning plate whilst riding a motorcycle etc).
They can be seen at many biking events in the UK and their performance is both entertaining and enlightening.
look at the funny motorcyclists with no clothes on, ooh how rude! They are called the Purple Helmets.

A popular alcoholic drink served especially in the "Companion" hotel bar in the town of Hearst, Ontario. It used to be made in the Palace Bar, but when that bar closed, the Companion took over serving it. I don't know exactly what is in it, it has something in common with Long Island Iced Tea, but it is called the "Purple Helmet" and it is a popular alcoholic beverage in Hearst.
Time for a pitcher of the Purple Helmet! C'est l'heure de boire un Purple Helmet! (in French too).

the body part that spouts a funny-smelling liquid and sits at the top of a long (from my experience, anyway) rod of pleasure. coincidentally, it also resembles shawn williams's head.
