Linking to a specific point in a YouTube video

….is explained very well here.
/////////////////////
Here’s a quick and confusing primer, mostly for myself:
The following should be appended to the end of a YouTube link:
#t=??m!!s
(In the above, ?? = minutes; !!=seconds)

http://www.youtube.com/watch?v=ePWjQ3DL-yI#t=00m39s
BONUS HACK: In the comments of the link at the top of this post, it also explains that adding the following will force the HD version of the vid to show (if available):
&fmt=18
