Mike Rotunda aka Irwin R. Schyster aka I.R.S. aka the lowest-paid wrestler on the SummerSlam 1991 Pay-Per-View made just $5100 ($5000 plus $100 draw) for defeating the second-lowest paid wrestler, veteran Greg "The Hammer" Valentine with an inside-cradle while countering Valentine's figure-four leglock. The Hammer's base-pay was also only $5000, but his draw was $200.
Additional Fun Fact: Of the eight matches on the card, only two saw the heels emerge triumphant. IRS defeated Greg Valentine, and the Natural Disasters defeated the Bushwackers. Three months after SummerSlam 1991 at the Survivor Series, IRS and the Natural Disasters would team up in a 3-on-3 elimination match against the Big Boss Man and the Legion of Doom.
