Gosh, I love this show. The main character is like a more likable Johnny Bravo who's a celebrity truck racer in a small town, and the show revolves around the ridiculous adventures of him and his friends, sometimes with high-speed car races, sometimes with run-of-the-mill things that get taken to some absolutely silly places. It's like Talladega Nights and Corner Gas had a magnificent stop-motion baby.
It's got tons of really silly, lighthearted humour, great characters & voice acting, and the animation is really well-done. Also, I'm a big fan of all the little original songs written for the show (mostly they're played in the end credits, but sometimes they're in the episodes themselves, and they're pretty entertaining). And it's good for all ages, so you can watch it with kids without worrying about the content. I definitely can't wait for a second season.
