#2. Robbie McAllister
Many members of the WWE Universe may have forgotten Robbie McAllister and his brother Rory, who were known as The Highlanders during their short stint in WWE.
McAllister competed on Monday Night RAW throughout the course of his WWE career, before there was some controversy when he attended a live episode of TNA Impact. Back in 2008 TNA was seen as a competitor for WWE, so when McAllister was spotted in the audience on live television, the company called him and told him to leave immediately.
Robbie did as he was told, but he was punished for his actions and the company went on to take away his $5,000 WrestleMania bonus. Less than four months after the incident, both Rory and Robbie were fired by WWE.
Robbie later went on to tell his side of the story to James Guttman at World Wrestling Insanity.
"Well, I don't really know exactly why I did it. I happened to go see my buddy Johnny Devine. He's a good friend of mine up here in Canada. It was my stupidity to actually go in there and watch it. In hindsight, I look at it as a set-up, but I'm the only one who knows (why I went). Do you know what I mean? Everybody else can speculate. Even Rory can speculate. It was my own stupidity. I don't even understand why I did it. But it could have been a subconscious thing that I did it because (WWE) weren't using us. Stuff like that. But it was just a dumb thing on my part. I wish I could take it back, but you never can. So now I just have to look and go, 'Oh well."
Given what happened to Robbie McAllister back in 2008, you probably shouldn't expect to see any WWE employees in the crowd at another company's televised event without them first getting permission to be there.
