In an interview with Talk is Jericho (via Wrestling Inc), Sabu said that many of his botches in his career were intentional to sell his gimmick of being crazy. Here are highlights:
On his in-ring style:
“I didn’t do anything in the ring that I didn’t practice. I wasn’t a crazy stuntman. I was a calculated wrestler, I would say. The trick was to make everybody think I’m crazy and I don’t know what I’m doing, but not the boss. So Vince [McMahon] and a few of the guys thought I was out of control which meant I did my job, but not really to them because they thought I was out of control but I wasn’t. But I never did any bump I didn’t already do in practice. Over and over.”
On using a chair to jump at opponents:
“That wasn’t spontaneous, just looked that way. I practiced that for months before I did it, I had the confidence to realize I could stand on the rope without falling.”
