I.M. Weasel creates an underpants time machine which I.R. Baboon steals and use to go back in time. I.R. is sucked by a time hole, and trying to be not sucked he holds Weasel's lab coat and they both back in time together. While traveling in time, I.R. inadvertently solves some history problems, such as make the dinosaurs become extincted and create the onion rings.—RTZ38
