#4 Delirious
Delirious is a simple wrestler with a simple gimmick: 90% of what comes out of his mouth is pure gibberish but spattered in there is 10% understandable language that makes him one of the funniest wrestlers active today.

Delirious is one of those wrestlers that know how to get a reaction out of the audience by doing very little. For example, in the link above, Delirious wrestles another gimmick wrestler named Player Uno, whose entire gimmick is centred on video game stuff.
So Delirious taunts Player Uno with ridiculous lines like: “blah blah blah…8 BIT”, “[incoherent rambling] Sega Genesis”, “blah blah blah Princess Peach is a tramp”. You can see how this gimmick works.
He basically acts as a Wildman, but hidden underneath those layers of supposed monstrous incoherence is a clever man that knows how to annoy his opponent and make his audience laugh...all of which make him an excellent wrestler.
