The Time Warp Trio: The Not-So-Jolly Roger
Sam, Fred, and Joe get sent back in time to when Blackbeard was a pirate. He captured the trio of time-travelers. They called themselves magicians. Then they proceeded to make it off the pirate ship, find "The Book" (which allows them to travel back in time, and come back to the present). Finally they made it back to the present, and they all got in trouble with their parents.
