#3 Eddie Guerrero Vs. John 'Bradshaw' Layfield (Judgement Day 2004)
One chair-shot. That was all it took to take this standard main-event of a SmackDown pay per view, into one of the most bloody matches of all time.
Already an emotional match, JBL, who had only recently transitioned from his Bradshaw character, was craving Eddie Guerrero's WWE title, and with the referee down, executed a chair shot to the skull to seal the deal.
Something went wrong along the way though, as Eddie bled buckets afterwards but was somehow still able to carry on the bout.
A DQ victory for JBL made that the title did not change hands, though Bradshaw would eventually capture the gold shortly after, but we'll get to that later...
However you feel about the company's current PG rating, this match shows why unprotected chair-shots should remain banned.
