What is Sarah Silverman Doing?

Or should it be whom? The BHK pointed me to this video, and it clued me into two things. First, Jimmy Kimmel and Sarah Silverman are a couple. I had no idea. I bet they laugh a lot, though, and that is good times. The second thing it clued me into was ... well, you'll have to watch the video for that. I couldn't help but laugh out loud when I watched it. That's right, I was actually LOL. Not ROTFLMAO or anything ridiculous like that, but I did LOL. Lesseee, this video is probably NSFW (the sound, not the actual images), so you should probably watch it at home or with headphones.
