Found out how to timestamp youtube videos

eg.

http://www.youtube.com/watch?v=k8TwRmX6zs4&t=0m33s

Not technically a timestamp, but rather deep linking, there are other URL tricks, but I'd like to see a more updated list than this one (as quite a few things have changed since then):

Ahh thanks, some interesting ones there.

Disable related videos looks interesting. Wasted too many hours watching sitcoms scenes only to turn out watching a whole episode from related videos.
