The cocky rant itself was tempting more fate — the next week he was drafted to Raw and minutes later quit his job.
A similar thing happened to William Regal during his phase as Raw's heel GM and King of the Ring, when he often blacked out the venue during fights and such. Well, with Regal on the verge of dictator, loudmouth Mr. Kennedy interrupts him asking for a fight. Regal responds, "The very next person who interrupts me, whether it be you or anyone else, will be fired on the spot." Guess who is the next person that interrupts Regal. And by the way, Regal would later lose his match versus Kennedy and get FIIIIIIIRRRRRRRRRREEED!!! as a result of Mr. McMahon's proposition.
Regal wasn't the first heel GM of Raw to meet this fate. When Eric Bischoff was the Raw GM a few years earlier, he opened Raw the night after the Survivor Series pay-per-view in an understandably bad mood as Raw's team had lost to Smackdown's team in a 5-on-5 elimination match the prior night. When nobody responded to his demand for an explanation of why they lost, he threatened to come back to the locker room area and fire whoever he saw on the spot. Cue the entrance music of Vince McMahon, the one person that Bischoff didn't have the authority to fire.
Any time a wrestler says something like "I could beat you with one hand tied behind my back!", you can bet the house that he'll be put in a match with such a stipulation.
Because Triple H, the WWE Champion, had been drafted to Smackdown in 2008, Smackdown had two champions and Raw had none. Edge, the World Heavyweight Champion, came to Raw to insult Jim Ross and Batista, who he had beaten the night before. He then proceeded to brag about how Raw had no champion, about how none of the top contenders would ever get a shot at his title, and how he would never come back to Raw. Unfortunately for Edge, he didn't count on Batista beating the tar out of him, or CM Punk (whom he had neglected to mention) cashing in his Money in the Bank briefcase to become the new World Heavyweight Champion.
During an episode of Raw in John Cena's hometown of Boston, Randy Orton pulled Cena's father out of the front row of the crowd and promptly punted him in the head. Cue Orton being on the receiving end of the most brutal beatdown Cena had ever administered to anyone in his career.
CM Punk himself managed two in the same promo in Ring of Honor during his feud with Raven: "Raven, where did being Extreme ever get you?", and "That beer you drink has never and will never touch my lips!" - after his dog collar match with Raven, Punk got jumped by Tommy Dreamer, tied to the ropes, and forced to drink beer. And three years later, he ended up in the revived ECW.
On the April 8, 2013 episode of Raw in the IZOD Center, the crowd is extra wild, chanting for just about everyone during Randy Orton vs. Sheamus, from referee Mike Chioda to Randy Savage. After that, they chanted for JBL and Jerry Lawler on commentary. JBL then states there's no way they'll chant for Michael Cole. Seconds later...
Whenever someone issues an open challenge and says he/she is ready for anyone on the roster, the result is usually being squashed by the biggest person in the company.
Averted, thanks to professional moron Vince Russo's incompetent booking style, by Vince McMahon going into the 1999 Royal Rumble. Austin got #1 and Vince got #2. Vince ended up winning when the Rock showed up to distract Austin when it was down to just him and Vince.
A recent example would be at Extreme Rules 2012 Pre-Show where The Big Show had to defend his Intercontinental Championship against former champion Cody Rhodes that was determined to be a Tables Match (where the only way to win is to put your opponent through a table). About 45 minutes into the actual show, Cody kicks Big Show's leg out from under him and he ends up stepping onto (and breaking, technically "going through") the table.
Big Show: (laughs) Good luck trying to get me through a table.
