Do you think Mr. Krupp ended up liking the Captain Underpants comic books after all?

It said in the first Captain Underpants book that Mr. Krupp especially hated those awful Captain Underpants comic books. Do you think once George and Harold hypnotized him into thinking he was Captain Underpants, after they changed him back by pouring water over his head that he ended up liking the comic books after all?
