Hilarious!!! Nice to see Matt has a sense of humor...and to see him dancing!?! Too funny!!

Check out Matt's moves! This is soooo funny, and it makes me love Matt Damon even more.

I thought of you Pop as soon as I saw this!! Funniest video ever! Matt is the best!

i love that gag and for the first time Sarah actually did her job, she made me laugh.

One of the things I like best about Matt Damon is he never takes himself too seriously, love it!

I love Sarah she always cracks me up!!!

this is awesome!

i LOVE sarah silverman...she's such a fuggin genious!

the duck looks good too. he actually has a sense of humor! sweet!

"Well, maybe compared to yours. Mine always showed up to custody hearings and rarely did she show her v@gin@ to the press."

– Jimmy Kimmel, responding to Paris Hilton's comment that Britney Spears is a "great mother," on his show
Now that was funny!!

HAHAHA! Brilliant! I'm glad that Matt, Jimmy and now Sarah can joke about not having enough time. I died! I must admit, Matt is pretty freaking funny!

just when i thought i couldn't ♥ matt damon more! funny and handsome...his wife is an even luckier b!tch! so jealous!

That was OUTSTANDING! Loved it.

That was really funny. They must have worked on it for awhile.

That just made me a fan of Matt Damon... hysterical!

That was so f***ing funny! Brad Pitt and George Clooney are going to be green with envy that their little buddy Matt Damon has one-upped them on the humor boat!

That was awesome!!!! Nice moves Matt!

That was amazing.
I love how Matt doesn't take himself too seriously, he's hilarious!

HILarious!!!! I love when MD sings/dances...remember when he was pretending to be gay and stole the lead vocal from Jack on Will & Grace??? Let's hear it for the boys!!!! =)

I love it!!! Go Matt!!

That was hilarious. Love Sarah and Matt for this. Great going guys.

I'm fu*ing Matt Damon

I have always liked him, but now I'm in L O V E

ahhh - i was watching Jimmy's show last night and this came on, I almost died laughing. Now I like Sarah (never really cared for her before) & I love Matt even more now.

This reminds me of Matt's cameo in "Eurotrip". The film itself wasn't exactly a masterpiece, but "Scotty Doesn't Know" still makes me laugh.

AWESOME!

I'm not a fan of Sarah, but this is f#$@ing brilliant!

I love Sarah Silverman , I even thought the Britney stuff was funny at the VMA's, call me crazy.

THIS WAS A CLASSIC! Me and my husband were on the floor

did jimmy not think it was that funnY? i thought it was funny, but it went on for long enough that it lost it's punch a little.

I LOVE Sarah Silverman. The end.

I don't watch the late night talk shows much anymore but I caught this on another site and it's hilarious. Im always torn about sarah, but she certainly had some funny moments on her show The Sarah Silverman Project , my favorite episodes were when she referenced The last dragon( complete with the fight scene music), the episode when she slept with black God, and the episode when she tried to be a lesbian.

HAHAHA I am not a big SS fan, but this made me LAUGH OUT LOUD!

That was hysterical! Matt Damon is so cute!

O.M.G!!!!! 2 fcuking funny!!!!! I MATTY!!!!!!!

I LOVE Matt! I don't think people have ever given him enough credit for how awesome he is! He always cracks me up!

I loved it!!! I like Matt Damon more and more.

I have tears in my eyes from laughing! That was great! I wasn't expecting to see Matt Damon and I loved how he referred to himself in the third person. His dancing was fantastic! Loved it!!!!

brilliant!!!!!!!!!!!

LOVED IT!

I love him!!! Not Sarah so much but that was damn funny!

Not a big Sarah Silverman fan but Matt made that worth watching!

that was the best thing i have ever seen! =D

LOL! i wonder what goes through Jimmys head whenever he watches this.

this video is the best. i like matt dancing and when his doing his solo singing. he can do good in kareoke. love him, he's great.
