Tom and Jerry were a pretty inferior example of cartoonery by the Hanna Barbera outfit, which never never came close to the imagination, range of characters, and outright multi-level humor of Warner Brothers creations.

The Simpsons lampoon Tom and Jerry regularly with the ultra-violent "Itchy and Scratch".

Nothing like pounding down a critter with a wooden mallet while making sure its lungs are in good working order.
