Could someone walk me through the process of linking to a certain spot in a video clip?

Often when providing links in order to support argument or further understanding on Fluther, I would like to link to a certain spot in a youtube video (or a video from another source). How can I link directly to minute 2:01, for example?

In addition, could someone describe how to link to a certain spot on a page? For example, the fifth page of a 20 page wiki document? Thanks!
