Al Franken just hurt me

So I'm listening to the O'Franken Factor this morning. Their guest this morning is a doctor who wants to take the Star-Spangled Banner to a different key--if it were sung a few steps lower, more Americans would be able to sing it.

His co-host Catherine asks, "But this was a drinking song originally, so why can't more Americans sing it?" Al starts singing in a drunken slur

You're such a great guy
And I... know your brother
He works with me
We cobble horses together

OK, so maybe you had to be here, but the guest was laughing, Catherine broke up, and I was in danger of falling out of my chair.
