John Ritter Dies

The sitcom actor collapsed while filming Thursday night, and died from "dissection of the aorta." He was 54.

While he was rather the opposite of Johnny Cash, he did serve the purpose of introducing my generation of pre-pubescents to the idea of permanent, unrequited yet undaunted horniness. And he was the one-man keeper of the pratfall flame after Chevy Chase left "Saturday Night Live."
