Chris Matthews, among many others, STILL quotes Ronald Reagan's "jokes"... especially "There you go again." Even today, it's still invoked on cable news as some sort of high watermark of political wit. Sarah Palin even clumsily quoted the line in a vice presidential debate, interrupting the flow of her clumsily saying everything else.
See, the reason we have videotape and Google and all that is so we can eventually realize that the people we made fun of at the time may have deserved better. Yes, Sinead O'Connor tore up a picture of the Pope on SNL, but do you remember why? It was to protest the Church's silence on the sexual abuse of children by priests. If it seemed funny and crackpottish to you at the time, does it still?
