Minute to win it game show?

What's up with every young girl/woman on Minute to win it wearing short shorts and low cut tops showing nothing but cleavage? And I'm sure push up bras to create even more cleavage. I wonder if any guys actually watch this show for the challenging games, or if they've even noticed what game was played? I'll bet the show would've been cancelled long time ago if all the young females were wearing overalls?
