Having Mankind hyping his upcoming return to an earlier, more fucked up incarnation (so as to get the crowd of Foley fans salivating for a return of Cactus Jack) -- and then bringing in Dude Love instead -- is one of the greatest examples of wrestlers fucking with the crowd.
I have folding chairs autographed by Foley as Cactus, Mankind and Dude Love (on three separate occasions). He seemed taken by surprise that anyone other than his kid would ask for a Dude Love autograph.
