5x2 - Ed, Edd n Eddy

Flashback episode that features alternate stories. The Eds try to make their way back to the place all the flashbacks began. In this journey many things are explained, including: Plank's chip (Plank got stuck in Rolf's teeth), and why Jimmy wears a retainer (the Eds tricked him into eating a bowling pin when he thought it was a cream horn).
