I see they got Kinky Friedman's "Get Your Biscuits in the Oven and Your Buns in the Bed" (the song that earned - and I do mean "earned" - him the Male Chauvinist Pig of the Year award from NOW), but how could they leave off his "They Ain't Makin' Jews Like Jesus Anymore"?
My all-time favorite is one written by my old guitar teacher, "I'm Dancing With Tears In My Eyes 'Cause the Girl In My Arms Bit My Nose."
