I Don't Get All Of John's Home Run Call For Lance Berkman (UPDATED THREE TIMES!)

It sounded like:

"Sir Lancelot rides the the rescue! C'EST LOUIS! C'EST LOUIS!"

I get the Sir Lancelot reference--obviously--but "C'est Louis?" "Say Louie?" "St. Louis?" What?

UPDATE: Am I the only one who heard the "C'est Louis" part?

UPDATE 2: Solved (I think):

Thanks, J Lam. But, still... what??

UPDATE 3: Oh, Christ. It's another Broadway reference. In Camelot, Sir Lancelot sings a song called "C'est Moi," meaning, of course, "It's me!" So, not being Berkman, John must say--no, cry--"It's him!"

Gaah, I have spent so much time on this. Thanks, John!
