Melissa McCarthy Was Willing to Get Dirty for 'SNL' Debut (VIDEO)

Say what you will about the writing quality or caliber of sketches on 'Saturday Night Live' (Sat., 11:30PM ET on NBC), but there is no denying that Melissa McCarthy gave as committed a performance as we've ever seen.

In some cases, she carried the laughs almost entirely by herself. She tackled physical comedy, like throwing herself down a flight of stairs multiple times, and wasn't afraid to get dirty, like in her explosive performance in the Hidden Valley Ranch sketch.

Her character was so eager to be the best taste-tester, that at one point she exploded an entire bottle of the dressing all over her face and chest, and just kept eating it and going on. To their credit, no one broke character during this hilarious moment, which was easily a highlight of the night.
