#1 Sami Callihan
Dean Ambrose may have once been the biggest lunatic on the wrestling scene, but in recent year's, Impact Wrestling's Sami Callihan has taken that mantle.
Callihan's notoriety peaked when he took out Eddie Edwards with a baseball bat, and the Impact star has run with that gimmick ever since.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
Ambrose, however, especially as Jon Moxley could easily give Callihan a run for his money when it comes to the crazy department.
The two men are both willing to put themselves through hell in the name of entertainment and with the pressure of WWE's PG-13 policy off his shoulders, Ambrose could really excel in a feud with Callihan.
