As hilarious as Michaels was here, he was also very unprofessional about the whole thing. Say what you will about Hogan, but he sure didn't go out there and sell like a goof when he was putting over Warrior. SummerSlam 2005 as a whole is such a bizarre show, from the opening match being 25 seconds long to the Eugene Invitational to the Ladder Match that decided custody of Rey Mysterio's son. Good grief. :
Yes, HBK was unprofessional here in this one. No doubt about it. However, this is a totally different situation from the Warrior/Hogan match, because that match was supposed to have been the passing of the torch. As where, HBK was pissed off at Hogan's lack of willingness to put wrestlers over. He did the same with Orton a few years later (or was it the next year?)
