How about this:

The Eds enlist in the Witness Protection Program after Eddy's brother swears vengeance. The Eds move to the town of Aberdale and give themselves new identities. Ed gains weight and renames himself Clarence. Edd undergoes plastic surgery to give himself a cube-shaped head and renames himself Jeff. Eddy shaves his head and calls himself Sumo.
