Classic evidence which I tend to bring up every now and then...
So during the 2003, the whole Test, Steiner, Kiebler thing. Test accidently hits Stacy/bosses her around and JR is all "Disgusting human being blah blah blah".
But then at Badd Blood 2003 (I think), for no reason at all Austin gives Mae Young a Stunner, and what happens? "Stunner! Bah Gawd Stunner!"
Nice.
