Fourth Grade (4x11)

Air date: Nov 08, 2000

The kids have to face the 4th grade, and they're not too happy about it. Cartman cooks up a scheme to go back in time to return to the 3rd grade where things were fun and easy. Two geeks help them rig Timmy's wheelchair into a working time machine and send Timmy on the trip of his life!
