Link to a specific part of youtube video

I know many of you probably figured this out a decade ago, but you can link to a specific part of a youtube video. Simply add #t=3m6s to the end of the hyperlink. (replace 3m6s with the timestamp you want.

For example  http://www.youtube.com/watch?v=BGX5U_8BfGs#t=12m50s will take you 12 minutes and 50 seconds into the video.

Now go tell your mother, she will be proud.
