This was so funny, I'm watching it a second time. I never do that with videos online. Well played, Sarah and Matt.

I never liked HuffPo doing entertainment and wished it would stick to politics, but I think this video has made me a convert.

THANK GOD THE WRITERS STRIKE IS OVER!

Oh, lighten up world. This is really funny. Sarah has her moments, but this was purely laugh-out-loud from beginning to end. Matt shows he's got balls enough to **** Sarah Silverman and punk Kimmel. Cerebral it's not. Payback is...well...you do the math.

I'd love to f**k Matt Damon, or better yet, he can f**k me!!

You know I can't decide who is les funny, Sarah Silverman or Gallagher!

...first, I LOVE Matt Damon...he's a phenomenal actor and seems to be a very level-headed guy with a terrific sense of humor...I admire how humble and down-to-earth he seems, in the face of all of his wonderful success...

...secondly, I HATE Sarah Silverman...she is completely useless and talentless, and I find her to be the definition of UNFUNNY....

...having said that, WHY is this funny?...really, why/how is it funny?...I didn't think Justin Timberlake's "Dick In a Box" was funny at all...and this "I'm Fucking Matt Damon" is even worse...

...dirty and crude don't and shouldn't always automatically mean funny...there has got to be an actual element of humor for something to be classified as funny--beyond words like "fuck" and "dick"...

...to quote Bill Clinton, "gimmie a break"...

You like this, good! Play it for the kids, they'll like it too.

Play it for your grandchildren, they'll probably click on it anyway when they see you've left it on the computer screen with the Huffington blessing.

Kids everywhere will be singing 'I'm f***ing Matt Damon at school.

It'll be the new "Twist," the new "Beatles," the new "Drawn Together" and "South Park."

Gimmee a break!

Love The Delano Hotel where this was filmed in South Beach, FL...!!! Too funny!!!

I usually can take or leave Sarah Silverman, but this was priceless.

Talent, good looks, a self-deprecating sense of humor - have mercy, Matt. :)

I'm dissapointed in myself for thinking this was so funny (but it was!) ;-)

I'm an angry little hater with an angry little life. Let me express that here in reference to the video. In fact I'll do that with a bunch of topics today. It's just who I AM.

I didn't watch this for days after it went up, but now I'm waiting for a client's call and had nothing better to do.

So glad I checked it out! Freakin' hilarious. Anyone who sees something political in this is a very angry and sheltered.

Haaaa!!

Hysterically funny!!!

I love Silverman.
