I know it was mentioned in this thread already (exactly two years ago as it happens
), but The Walls Of Jericho became a simple Boston Crab over time. The original version looked more different and cooler. 
I NEVER understood the change. I remember when it first started happen, it was sort of in a botched way, like he didn't mean to but the guy was too big. All I can guess, is when he did it in WCW, perfectly, it was nearly always on cruiserweights, often on smaller guys, and in WWE, trying to put it on a Big Show....Batista....Kane etc. just doesn't work to well, that's my only guess. But yeah it was awesome when it was known as....The Liontamer!
