My bro-in-law gave me "Wigfield" on audio, read by the authors. Pretty funny, but tiresome after a while. I can't listen for more than half an hour in one city-- the narrator and characters are just exhaustingly dumb, or maybe just the writers are exhausingly clever.
One city?
And yeah, the joke thins out after a while, but definately had some "out loud" moments.
Yup-- I usually listen on the bus, heh. And you're right, I've received a few stares thanks to some barely-stifled chuckling while listening.
