Mechanics puzzle

Here is a nice mechanics puzzle: provide an example of the body which has non-zero momentum but whose kinetic energy is zero.

So far only one of my fellow physicists found how can it be. Feel free to leave your versions in comments. If you gave up, watch the 16th lecture by prof. Walter Lewin of MIT.

Anyway, Lewin's lectures are awesome!
