I have it on good authority that the internal infection that Vince had was the WWE creative team.
Apparently he caught a rare bug called 'TheRealityOfSmackdownViewing' and like many of us, felt too sick to watch the Great American Bash.
Rumour has it that he tried to change the rosters over at short notice, but Shawn Michaels was unable to put together a John Cena style Rap in time.
