1. Jeremy Piven
https://www.youtube.com/watch?v=CJAfMt20M2Y For me this was the ultimate blooper by a celebrity guest. In another example of the host forgetting their lines, Jeremy Piven threatened John Cena that he could be banned from SummerFest although I'm sure that wasn't of too much concern to Cena with SummerSlam just around the corner. Busch could perhaps be forgiven by his aforementioned blunder, given that Kofi "Johnston" Kingston had only been on the roster for a couple of years at the time. But for Piven there can be no excuses SummerSlam has been around for decades, and this was an example of a celebrity host coming on the show despite a complete lack of interest in the field of professional wrestling.
