Songs stuck in my head (whether I want them there or not)

The first one is the one that's been making the rounds practically everywhere, and which I first saw courtesy of rabbitucker. That would be J*** In My Pants. Let's just call it NSFW, to be safe.

The second one is Cooking By The Book, Lil Bigger Mix. Definitely NSFW, because Lil Jon. That freaking Lazy Town song is catchy enough as it is, but the absurdity to be found here by mixing in Lil Jon just puts it over the top. The only exposure to Lil Jon that I've had prior to this, such as it is, has been thanks to Dave Chappelle, and I can't say that actually seeing/hearing the real deal now has made me a fan at all, stuck in my head though it may be. (Fair warning, Youtube has been cracking down on the mash-up videos, but people just keep putting it back up, so if the previous link is gone, just try doing a Youtube search and you'll probably find a new instance of it. Assuming you want to, that is. ¬_¬)

The third one has been in my head off and on since bloody August: Trudgemank. It just won't leave. Luckily, this one's SFW at least.
