Steven mentions that his sister Hayley was giving the coach a Rod Carew in the parking lot. Rod Carew was a Major League Baseball player for the Minnesota Twins and California Angels in the 1970s and 1980s. In addition to being the only major leaguer to ever be born in a train, he was one of the most prolific hitters of his generation. It should be noted that Steve is using R"od Carew" as rhyming slang for "screw".
I agree with you that Garfield is good, and just because he isn't a household name doesn't mean he won't be. Who was Hugh Jackman 10 years ago? That being said, I liked Spacey as Lex. The movie that wasn't that great, but I don't blame him.
