They are bringing back Wipeout. It's a human obstacle course where people are basically catapulted into mud or water. The official ABC site describes it as:
Human cannonballs! Human pinballs! Crashes, smashes and mud splashes!The contestants compete across several weeks to win a grand prize of $50,000. After taxes, isn't being a human cannonball worth more than that? Your programming choices make me sad ABC, very sad.
