"Of Rice and Hen" (McKimson; 1953):

ABC: This was cut: Foghorn readies to put lit dynamite in the dog's doghouse, and the dog grabs his house and places it over Foghorn, who receives the effect of the explosion underneath the doghouse. Later, Foghorn and the dog, who is disguised as another rooster, fight by hitting each other with their swinging fists, and after winning the hand-to-hand combat, Foghorn steps on the fake rooster's stomach as he walks away with Prissy from the fight site.
Nickelodeon: The aforementioned fist-fight was trimmed to be less violent.

"The Old Grey Hare" (Clampett; 1944):

CN: The new, standard "Dubbed Version" ending card has replaced the original one that "shook" in reaction to a dynamite blast incurred by Elmer Fudd, but the explosion sound effect can be still be heard on the audio track portion.
WB: Removed as the part wherein baby Elmer points his cork gun at baby Bugs' face and baby Bugs then smashes his bottle of carrot juice over baby Elmer's head.

"One Froggy Evening" (Jones; 1955):

ABC: The sign that reads, "Free Beer," that is placed outside of the theatre in the man's attempt to attract customers was excised.
WB: Same edit as on ABC.
