From all the way back in 1944 comes this screwball cartoon "Batty Baseball" from legendary Warner Bros/MGM animator Tex Avery. Avery was well-known for creating the character Daffy Duck, who he modeled off one of his friends with a crystal meth addiction.
Although it uses some pretty cheesy sight gags and puns, "Batty Baseball" had enough prurience and violence to make it enjoyable and completely inappropriate for overprotective parents to show their kids nowadays. So I wholeheartedly approve.
