Will Ferrell's Hilarious Performance On 'SNL' Makes Everyone Break Character

One of the hardest things about live television comedy must be not cracking up in front of the cameras when something's really funny. Which is why we have to give props to the cast of Saturday Night Live, who deliver some of the funniest sketches on TV every week and generally keep it together. But not always:

As you can see, largely thanks to Will Ferrell's over-the-top performance as a new reality TV star who's changed dramatically since moving to LA, the cast had trouble staying in character because they were constantly on the verge of breaking into laughter.

Ferrell and Cecily Strong played a Real Housewives-esque couple who had popped back - with their dog Peanut, who 'doesn't walk' - to their hometown of Flagstaff, Arizona . Not only had they had ample amounts of plastic surgery, but they'd clearly fallen into the trappings of Hollywood life and all its fake tan glamour.

One her Instagram account, Strong posted a picture of her and Ferrell (and Peanut) with the following caption: "I told Lorne after the show that I might have broken during this sketch. A comedy hero and a dog hero and lil ol me with a bad face lift gave me one of my favorite moments foreva eva.

"Like, this is one of those where on days where I'm not feeling great, I can watch this on YouTube and I'll start laughing a bunch."

'Lorne', by the way, is the show's 73-year-old creator, Lorne Michaels.

We're just impressed they held it together as much as they did. We probably would have been on the ground in stitches from the off. But then again, that's why they're professional actors and comedians.
