Do you think you can come up with a good line for Barney (Neil Patrick Harris) to use on How I Met Your Mother? Here's your chance.

CBS and TV.com are having a contest to find the next Barneyism that everyone will be repeating to their friend. And if you win, the Barneyism you write will actually show up on a future episode of the show.

I've only seen a couple of episodes of the show, so the only one that I know is the "Suit Up" line. I guess that's the best known. If you think of a good one, put it in the comments below. And if you win, let us know.
