Scrapheap Challenge: The Scrappy Races

I watched a reality TV show and liked it… yes, I know, the world will be ending shortly. I blame my brothers for this. Scrapheap Challenge: The Scrappy Races features small teams of engineers scavenging a scrap-heap and building things to complete challenges. I just saw an episode where four different teams tried to design devices to a) capture a fake sheep and b) launch it through the air into a pen. Claw, Spike, Net and Noose followed by Giant metal throwing arm, Air cannon, Rail gun and Centrifuge throwing arm. I wanted there to be a trebuchet so badly.
