Did you know/98
From A Wiki of Ice and Fire
... that Ser Patrek of King's Mountain is a reference to Patrick St. Denis, who runs a fantasy website called Pat's Fantasy Hotlist, and was included because George R. R. Martin lost a bet to Patrick? Patrick is a fan of the Dallas Cowboys, while Martin is a fan of the New York Giants. The bet was that, if Martin lost, he would have to kill Patrick horribly in the book. Ser Patrek's coat of arms is described as looking somewhat like the logo of the Dallas Cowboy,. and Patrek is eventually killed by Wun Wun, a giant, in A Dance with Dragons.
