Identity Thief opens in theaters today and based on the trailer, it seems that Melissa McCarthy will bring the funny with her co-star Jason Bateman. (Actually, it is guaranteed because I saw it and it was magical.) Even so, Melissa has been bringing the funny to Hollywood for a while now. Before her Academy Award-nominated role in Bridesmaids and her TV roles in Gilmore Girls and Mike & Molly, she was showcasing her comedic chops. Even though she wasn't a headliner in the these movies and TV shows, she certainly stole every single scene she was in -- and it paid off. She is now one of the funniest ladies in movies and television...and I thank God for her every day. Check her out in these bit parts:

In the short-lived Samantha Who?, Melissa starred as Dena, the title character's (played by Christina Applegate) childhood friend. Even though she didn't poop in a sink while in the series, she was still damn funny!

For a split second, we get to see Melissa as a chipper office worker in Charlie's Angels. Then she calls Lucy Liu a bitch. So naughty!

In Go (one of THE best movies of the late '90s -- when raves were TOTALLY cool!), Melissa appears on-screen for a very limited amount of time with Jay Mohr and Scott Wolf -- and she owns every second with her awkward giggles and ditzy charm. It is one of the funniest moments of the movie. (Fast forward to timestamp :57 if you want to go straight to her bit).
