1x24 - Cow and Chicken

Flem's Dad takes Chicken, Flem, and Earl on a camping trip in the woods. Cow shows up with Chicken's forgotten hairbrush, only to be kicked out by him, Flem and Earl. Flem's Dad then sings a ballad to the kids about a flattened cat, who can act like a frisbee, and cut things down like trees and trucks. Later that night, the kids find their cans of Sugar Frosted Weenies cut open by Sailcat.
