Adolf Hit By Tomato

The first cartoon animation legend Tex Avery directed for the MGM studio was "Blitz Wolf" (1942), a World War II sendup of the 3 Little Pigs fable. The Adolf Hitler wolf breaks the 4th wall and addresses the audience (an Avery trademark), and is promptly pelted by said "audience" with a rotten tomato.

Boom Goes the Dynamite

From "Jerry's Cousin" (MGM, Hanna and Barbera, 1951). Jerry's tough-guy cousin, Muscles Mouse, demonstrates what happens when a firecracker goes off in Tom's mouth.

Kicking under the Mistletoe

Despite spending their entire careers plotting to kill each other, Tom and Jerry do have moments of cuteness. They just don't last long, as shown in these two images from "Night Before Christmas" (MGM, William Hanna and Joseph Barbera, 1941).
