I know the actual message goes on about him not being here..there..etc. But I think his best message, and one of his best lines, is when Jerry and Elaine return from seeing Frank Costanza's lawyer in a cape and George leaves a message on Jerry's machine (with me so far):
"Hey it's George I've got nothing to say."
True Costanza defeatism, a true man of the 90's.
Everyone listens to the Chinese.
