Co-Sign. I also think that Booker T's "Tell Me, You Didn't Just Say That" never got old either.
Honestly John Cena's "You Can't See Me" thing is so damn old he really needs to drop it all together the only time it was cool was during the Word Life era.
None of Cena's catch phrases ever get old IMO because he is so damn epic
that was regal who said all hail king booker
