An entertaining topological party trick that I have seen performed is to turn your pants inside-out while having your feet tied together by a piece of string. For a demonstration, check out this video.

I have heard some testimonial evidence that it is also possible to turn your pants *backwards*, again with the constraint of having your feet tied together. This second claim seems pretty dubious to me.

**Question.** Is it indeed possible to turn your pants backwards, while having your feet tied together by a piece of string? A set of instructions or a video demonstration would suffice for a yes answer. A precise mathematical formulation of the problem together with a proof of impossibility would suffice for a no answer.
