Dome Gnome, Go Home
Shelby, You're Fired!
No Great University Wages War on Its Faculty--Neil McMillen
Shelby Thames: USM's Own Weapon of Mass Destruction
Academic Freedom: 433; Shelby Thames: 32 (or whatever the exact numbers were from the No Confidence vote)
You can get a t-shirt with the Polk quote on it, along with a picture of a foot with four toes and a band-aid. See the "something amusing while we wait" thred for the contact info.
