Graham Ross has grand plans for world domination through his illustrated inventions. Right now he's having a "ball" hanging out with Billy Sure, the next sure thing! Graham lives in a little log home in the woods with his inventive family, just outside of Merrickville, Canada. Luke Sharpe is not a millionaire, but he has been trying to invent a machine that can teleport people anywhere in the world since he was eight years old. He has so far been unsuccessful but he has vowed never to give up. When he isn't working, Luke enjoys Hawaiian pizza and skateboarding. He lives near Chicago with his wife and son (named Billy, of course), their gecko, Eddie, and their aquarium full of exotic fish.
