In the short, Speedy tells another mouse, José, about some of his and Daffy's exploits, which are illustrated by clips from earlier cartoons.
Plot
Sitting in front of a broken television in a junkyard, Speedy Gonzales encourages a young mouse named Jose to watch "imagination TV." "The stupidest creature on Earth has always been the duck," Speedy says, "and the smartest is the mouse." Speedy and Jose imagine the evidence, in the form of scenes from the following cartoons: Robin Hood Daffy,Tortilla Flaps,Deduce, You Say,Mexicali Shmoes, and China Jones.
Daffy has been watching them, and emerges from behind the broken TV and hits Speedy on the head with a mallet. Daffy calls Speedy a stupid mouse and himself a smart duck. Speedy says he will go home now, stating that "this imagination TV gives me the terrible headaches!" Jose says: "It looks so real. Could it be my imagination?"
