The Chandler wobble is a small deviation in the Earth’s axis of rotation relative to the solid earth,[1] which was discovered by American astronomer Seth Carlo Chandler in 1891. It amounts to change of about 9 metres (30 ft) in the point at which the axis intersects the Earth’s surface and has a period of 433 days.[2][3] This wobble, which is a nutation, combines with another wobble with a period of one year, so that the total polar motion varies with a period of about 7 years.

The Chandler wobble is an example of the kind of motion that can occur for a spinning object that is not a sphere; this is called a free nutation. Somewhat confusingly, the direction of the Earth’s spin axis relative to the stars also varies with different periods, and these motions—caused by the tidal forces of the Moon and Sun—are also called nutations, except for the slowest, which are precessions of the equinoxes.

So, maybe we could get a really long cable and tie it or bolt it to something to hold Chandler Bing in place, so's it couldn't wander around and wobble and stuff.
