Cristin Milioti: Watch the '30 Rock' scene-stealer's 'Sopranos' past

The Feb. 24 episode of "30 Rock" was, for lack of a better term, a perfect storm of awesome.

Not only did "Let Me In" star Chloe Moretz show up as ruthless, Bieber-loving, aspiring businesswoman-child, "TGS" almost got a new writer in Abby Flynn (Cristin Milioti).

Playing an up-and-coming stand-up comedian, with pigtails and a baby voice, Milioti kind of stole the episode for us -- if you ignore, for a moment, the sight of Alec Baldwin in an old sea captain's uniform.

But we couldn't help but wonder, under the wig and, ahem, cleavage... why Milioti looks so familiar. Enter: the Internet.

Milioti is a three-time "Sopranos" vet, playing the very small, but distinctly hilarious, role of Catherine Sacrimoni, which you might remember best as the grumpy bridesmaid in "Mr. & Mrs. John Sacrimoni Request."

Though her shining moment ("God! Can't this family ever talk about anything besides food?") doesn't seem to be on YouTube, you can watch her look shocked when her mother keels over at the worst wedding ever.
