Genie, the
Considered a way to impress mates. Take a new box of matches, light one and stick it back into the partially open box with the others. Quickly, step well back and hold breath in expectation of huge pyrotechnical display. Sigh, at the tiny puff of acrid smoke. Net result, a millisecond of crap entertainment and no matches left to light to light your fags. Friends gained: none.

With my trademark genie-us, I once hung a box of matches from a smoke alarm with blu-tac & thread and then genied it - the idea being that we'd get a break from PE and the evidence of my prank would burn itself away to nothing. (Like the man who hung himself by putting a noose around his neck and standing on a block of ice.)
The actual result was that (rather obviously, in hindsight) the thread caught fire, the genie burned a hole in the carpet and i got a bollocking.

Similar to this, but called "Black Man's Willy":
Take two matches and push them into the end of a matchbox (one either side) so that their heads stick out. Wedge another match between them so that its head is touching one of the others. Like so.

Light it, and stand well back! No, further back than that! This is dangerous!
The wedged match will magically stand up, and blacken like a funny-faced brown's engorged member. Black Man's Willy - see?

The Dragon
Basically a genie, but one tears out a small square from the inner and outer parts to the matchbox on the side where the match heads sit. Then apply lit match in similar fashion to the genie but, and here is where the dragon becomes wildly more daring, stick the lit match through the little square hole. Result? A burst of directed flame almost exactly (un)like a burst of flame from a grumpy dragon's cave.

Friends carring matches in a trouser pocket provided the raw material for an invisible, yet more rewarding genie. Give them a good big kick in the match pocket, dragging your foot down on impact. There was a one in ten chance of a genie going off in the pocket, causing some "Jesus" and "fuck". If the genie didn't go off, at least you'd kicked someone.
Similarly, friends gained: none.
