Writer's Block: American idol

What is the one song you must sing at karaoke?

I'm not a karaoke person at all. AT ALL. But, if I have to sing any song aloud it's usually when I'm drunk and there really are only three options:

Khe Sanh by Cold Chisel, We Are The Champions and Bohemian Rhapsody by Queen.

Y'know, 'cause I'm a classy mufukka.
