"Girls" star Allison Williams turns 27 on 13 April. With a starring role in "Peter Pan Live!" and the main role in the HBO comedy "Girls", Williams is tasting sweet success in showbiz.

Williams, who is engaged to Ricky Van Veen, the co-founder of "CollegeHumor", the comedy website based in Los Angeles, is best known for playing Marnie Michaels, one of the lead characters in "Girls".

Arguably the most mature one in the four-women group, Marnie also gets to say some of the straight-faced, relatable, yet funny dialogues of the show.

In celebration of Williams' 27th birthday, here are some of Marnie's best quotes from "Girls":
