You have a long strip of paper, one piece of tape, and some scissors. You must create two paper rings that are linked. The catch is that you must use the tape before touching the scissors, and you may not tear the tape or paper.

A drawing of the rings?  Not very likely.  But I can help you envision it.

Imagine a ring of paper, made by taping the two ends of a strip of paper.  If you were to give it a half twist, you would get a moebius strip.  Here's a picture of a moebius supplied by mathworld, and I just found out that you can rotate it with your mouse.  If you gave it two half twists, you would get the twisted ring that we want.  If you cut down the middle of the twisted ring, you would get your linked rings.  Hopefully, this at least gives you enough understanding to recreate the rings yourself, at which point you shouldn't have to be able to imagine it.

Of course, there are other methods that are perhaps explained in other people's comments
