The process of filling the 36 spots on the Dallas Cowboys' iconic cheerleading squad began this weekend, with 300 lovely and ultra-fit ladies attending an open tryout in Dallas.

The squad won't be finalized until closer to the 2011 NFL season (assuming labor issues don't wipe the season out, anyway).

Watch the video of these wannabe-cheerleaders trying to impress with their gyrations. (You can also check out photos from the tryout here.)
