They are all from Youtube. Here are the accounts for the first and third one.

The second one's account has been gone for awhile now. There was sound for the second clip, but I can't find that clip, I just have it without sound right now. Also on the third link, there are a bunch of clips with women taking their pants off. It's a Czech (I think) radio station that did some pants removal promotion. I'm not too sure, but I'm not complaining, LOL.
