Mucho Locos is a 1966 Warner Bros. Merrie Melodies cartoon directed by Robert McKimson.^[1] The short was released on February 5, 1966, and stars Daffy Duck and Speedy Gonzales.^[2]

In the short, Speedy highlights some of his and Daffy's previous exploits. It was the only cartoon in the series where Daffy gets the upper hand at the end. It was also the final appearance of Porky Pig in the Golden Age of American Animation. Porky appears in the Robin Hood Daffy segment. It is the only cartoon to have Porky Pig and Speedy Gonzales in the same film, although the two never interact.

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 claims, "and the smartest is the mouse." Speedy and Jose imagine the evidence, in the form of redrawn scenes from the following cartoons: Robin Hood Daffy, Tortilla Flaps, Deduce, You Say, Mexicali Shmoes, and China Jones.

Unfortunately for Speedy, Daffy has been watching the whole time, and emerges through the broken TV and hits Speedy with a mallet for the insults. Daffy calls Speedy a stupid mouse and he called himself a smart duck. Speedy decides to go home, stating that "this imagination TV gives me the terrible headaches!" This gives Jose something to ponder: "It looks so real. Could it be my imagination?"
