The WWE has a, shall we say, complicated history of using celebrities in the ring.

With all due respect to his wife, this burning passion isnt for one person.

Given Shaquille ONeals recent surprise participation inWrestleMania 32, just dont expect this trend to end anytime soon.

Here are examples of some of the most memorablefor good or illcelebrity appearances in the WWE.

1) Mr. T teams up with Hulk Hogan against Rowdy Roddy Piper and Mr.

Outcome and aftermath:The good guys won, of course.

This helped validate Vinces pushing of big-names and now we accept and expect them at events likeWrestleMania.

Mr. T also returned the following year for a short and fairly forgettable boxing match against Piper.

An undeniable icon like Aretha singing a beloved, patriotic anthem guaranteed a special moment.

In the end, his biggest contribution was kicking Jeff Jarrett.

The contest ended when LT pinned Bam Bam following a flying forearm from the second rope.

A fair amount of mainstream press covered this at a time when the then-WWFs popularity was starting to wane.

Even still, some wrestling critics thought Taylor performed reasonably well.

Steve Austin standing up to the former champ helped cement the fearless image of Stone Cold.

The eventual outcome atWrestleManiasaw Tyson turning on Michaels and aligning himself with a victorious Austin.

Outcome and aftermath:Carey stood around watching others fight until he was nearly choke-slammed by Kane.

He narrowly escaped, thanks to an intervening Raven, and then eliminated himself.

He later became one of the most derided members of WWEs Hall of Fame Celebrity Wing.

He even tried to stretch his dubious fame out a little more with a rap album.

Outcome and aftermath:Flash ahead toRawon New Years Day 2007.

Cena returned later in the broadcast and beat down Federline.

A rivalry developed by 2007, leading to The Donald dropping cash onto ecstatic fans duringRaw.

Vince pumped a lot of hype into aWrestleMania 23match dubbed Battle of the Billionaires.

Trump then gleefully shaved Vinces head as Austin held his boss down.

Before long, Austin turned on Donald and gave him probably historys most surprising (and awkward-looking) Stunner.

While Show hyped himself in the ring, Rey Mysterio hobbled around the floor following a loss to Edge.

The resulting flurry of punches bloodied Shows nose and set up a No Disqualification match forWrestleMania XXIV.

The final blow came courtesy of a brass knuckles-assisted punch that knocked out Big Show.

During a red carpet interview onExtra, he challenged Chris Jericho to a wrestling match.

Days later, they both appeared onLarry King Live.

Rourke downplayed his remarks, while Jericho seemed intent on a match.

The live audience loved it, but serious fans again grumbled about a wrestler taking a beating from non-wrestler.

As a means for promoting it, they appeared on that years Halloween edition ofRaw.

Outcome and aftermath:WWE superstars interact with Grumpy, taking selfies with her and carrying on one-sided conversations.

First, there was the unusually long build to their showdown.

Then there was the heavy involvement of social media.

Stardust got into dedicated wrestling fan Amells face during a Memorial Day episode of Raw.

Outcome and aftermath:A lifelong wrestling fan, Amell took the match and his preparation seriously.

Amell then shoved Barrett into the ring for Nevilles finisher and the win.

With the referee knocked out, Stewart entered into the ring.

Cena responded by picking Stewart up and dropping him with an Attitude Adjustment.

WCWs Famous Guest Spots

WWE is not the only blinded by Hollywoods dazzle.

Before it imploded, WCW often borrowed a page from its rivals playbook,often to unintentionally hilarious results.

At times, the company even went to lengths not even Vince would dare go.

Along with his wrestling skills, hes often lauded for always doing what his employers needed.

At WCWs Capital Combat in 1990, that included pretending an agonizingly slow RoboCop was real.
