"we saw it when Bill Mahrer lost sponsors for saying the terrorists were brave"
"we saw it when the Dixie Chicks got boycotted for saying they were ashamed of President Bush."

One of these things just doesn't belong,

By the time I finish my song?

Oh, and just so you know, the Secret Service isn't Congress.
