I'm a little older than some of you posting, with that in mind...
Tully Blanchard vs Dusty Rhodes - TV Title vs $100,000 Match - June, 1987 Blanchard was TV champ, and as such offerred 10 grand of his own money to anyone who could beat him in a title match, the catch was he usually only allowed 10 minute time limits. Rhodes wanted a 60 minute time limit and to get it he put up $100,000 of his own money vs Blanchard's title. The two wrestled a great, half brawl, half technical match that lasted nearly the entire hour long episode of NWA SuperStars. In Dusty's corner, holding the money, was Magnum TA, making his first appearance since he was crippled in a car crash almost 10 months earlier, hobbling to ring side on a cane with use of only one arm (that was legit, it was not played up for storyline purposes). Just as it loks like the time limit might expire, Dusty rallies and appears on the verge of victory when Blanchard's partners in The Four Horsemen (Arn Anderson, Managaer JJ Dillion, and I believe Lex Luger) show up and start to BEAT UP POOR CRIPPLED MAGNUM!!! Even by today's jadded standards the idea of these guys beating up a cripple let alone a guy who was one of the three or four most popular wrestlers in the country before his accident, was heinous. To this day, best moment of villainry the Horsemen ever had, ranks right up there with the NWO locker room invasion as one the great heel moments for a group on wrestling TV.
Of course Dusty can't let his buddy get beaten down by these thugs so he leaves the ring and valliantly fights off all three guys but is counted out in the process, Blanchard keeps the title AND wins Dusty's money. Priceless moment for the bad guys.
Of course Dusty got his money back (In a barbed wire, no holds barred, Ladder Match of all things, little ahead of their time, that sounded like something ECW would have done 10 years later) but the surprise appearance by Magnum, the quality of the match, their past history of violent feuds, and sheer ruthlessness of the attempted beatdown make this one of my all time fav non PPV/Annual Event televised matches.
