I was going to make today's question the opposite of yesterday's and ask about the best in the business as far as broadcasting goes, but I probably wouldn't have accepted any answer other than Jets' Radio broadcaster Bob Wischusen, so I decided against it. Instead, in honor of the fortieth anniversary of Nicole Kidman's birth:

What is the best thing to ever come out of Australia?

Yesterday's champ: I've gotta give it to O-Train just because of the Harry Caray anecdote

You can't talk about a "homer" without mentioning the name Johnny Most, the legendary Celtics broadcaster. Fans would mute their televisions and listen to Most's broadcasts and swear that two different games were happening. Crowing in his trademark raspy voice from "high above courtside," he might be the only broadcaster to drop a lit cigarette in his own lap during a live broadcast.

Most was a "homer" in every sense of the word, and was downright vicious towards opponents (for example, he frequently referred to Magic as "Crybaby" Johnson). Perhaps his most famous call was during the playoff series vs. Detroit:
"There is a violent, violent knockdown by Laimbeer and Bird just smacked him! Oh my! Oh, the yellow, gutless way they do things here! They have been called a dirty ballclub and I can see why! This is a typical, disgusting display by Rodman, Laimbeer and Isiah Thomas! And they told me I shouldn’t say bad things about Isiah and I say ‘why not!’"

My honorable mention goes to the great Harry Caray, who rooted for the Cubs, but broadcast like a true fan. For example, Cubs OF Jorge Orta dropped the ball once, inspiring Caray to say, "How could he lose the ball in the sun? He's from Mexico!"
