#4. PJ Walker defeats IRS
IRS is the father of current WWE Superstars, Bray Wyatt and Bo Dallas.
Back in the early '90s, he was one of WWE's most hated heels, a character based on the US Inland Revenue Service (hence the acronym IRS). Regularly chastising fans and his fellow WWE competitors as tax cheats, he'd order that they pay their fair share, or face the consequences!

As well as being one half of the tag team Money Inc. alongside Ted DiBiase, IRS also enjoyed several years in WWE as a singles star - even winning the Intercontinental Championship at Royal Rumble 1994, only for the decision to be reversed seconds later.
However, IRS was actually a victim of a major upset in WWE in 1993. At the time he was feuding against Razor Ramon, who made his way to ringside during IRS's match against unknown wrestler PJ Walker.
Ramon proved to be a major distraction to IRS during the encounter, and Walker - who later had a successful career as Justin Credible - took advantage by rolling him up for the pin and the win!
