His now legendary "Austin 3:16" promo upon winning the 1996 King of The Ring, forever cementing his place as a future legend.
Austin: Austin 3:16 says "I just whooped your ass!"
Bret Hart vs Stone Cold, Wrestlemania 13. The end of the match had Hart putting on the Sharpshooter on Austin, and Austin is bloodied and desperately crawling to the ring ropes and passes out in a pool of his own blood. That iconic image would be the start of Austin's Wrestlemania moments of glory.
The fans' support for Stone Cold's refusal to tap to the Sharpshooter, despite being a heel, is what would more or less jumpstart his turn to fan favorite and resident badass of the WWF.
There's a moment when Austin begins to pull himself up as if he is going to break the Sharpshooter, and the blood really starts to pour down. The fan response is chilling.
The match that started the Attitude Era- "Stone Cold" Steve Austin vs. Shawn Michaels at Wrestlemania 14. Specifically the ending- A sweet chin music which was countered into a stunner which was countered into another sweet chin music which was countered into another stunner!!
A standout moment: Austin finally gets to wrestle Vince, in a steel cage no less, at St. Valentine's Day Massacre in 1999. It quickly degenerates into a bitter employee rather callously kicking his boss' assall over the arena. At one point, Vince is flung from the top of the cage through the Spanish Announce Table, and when Howard Finkel attempts to announce Austin as the winner by forfeit, Austin rightfully points out that the match hadn't actually started yet. Rarely is that level of sadism so awesome.
Austin: Now, jackass! Jackass, that's you in the black! Is the son of a bitch still breathing? Well, since he is still breathing, if you want me to finish this can of whoop-ass, gimme a hell yeah!
Memphis: HELL YEAH!!!
Any time he gets behind the wheel (a monster truck, beer truck, The Rock's Cadillac, cement mixer) one can expect this. The most awesome is regarded as when he drove a zamboni up to the ring so he can fly over the cops protecting Vince McMahon.
A moment that may rival the awesomeness is the beer truck. Austin drives a beer truck to the ring, and cuts a fantastic promo on the Rock.
His even greater Big Damn Heroes moment, Stone Cold returning to his old self in 2001, saving Team WWF from the Alliance, entering to a truly massive pop. Check it out here
But the best ever Big Damn Heroes moment? Showing up on Raw after a brief absence, to help Mick Foley win his first title over The Rock, and in the process receiving, quite possibly, the loudest crowd reaction in Raw history. It's glorious.
The Raw after Survivor Series 2001 was a simultaneous CMOA for Austin and Ric Flair. For Flair, it was his return to the WWF after so many years and becoming business partners with Vince. For Austin, it was his almost effortless Heel-Face Turn one night after leading Team Alliance against Team WWF in the Survivor Series. Turns out that beating the crap out of a Dirty CowardKurt Angle makes turning face real easy. Observe.
A championship match on Raw between him and The Undertaker received a 9.1 rating and a 17% audience share, by far the highest rated segment in Monday Night Raw history (yes, even higher than "This is Your Life", despite all insistence to the contrary).
