From the same source as the last post.
The five guys named their goat, get this, Wrigley.
In case some of you aren't particularly baseball fans or Cub fans, here's the downlow on the infamous CURSE.
The Chicago Cubs have the Curse of the Billy Goat on their heads.
The Curse of the Billy Goat was issued before Game 4 of the 1945 World Series. William "Billy Goat" Sianis, owner of the Billy Goat Tavern & Grill in Chicago, arrived at Wrigley Field with two tickets-- one for himself and one for his good-luck pet goat. (Remember the Billy Goat Grill from that hilarious SNL sketch "Cheesboiger, cheesboiger, cheeps, no fries.")
According to tavern history, ballpark ushers stopped Sianis from entering, stating that animals weren't allowed to enter the ballpark. (I don't know, but I've known some Cub fans who might qualify for that title.)
Frustrated, Sianis appealed to Cub owner P.K. Wrigley, who replied, "Let Billy in but not the goat. That goat stinks."
Legend has it that Sianis threw up his arms and exclaimed, "The Cubs ain't gonna win no more. The Cubs will never win a World series so long as the goat is not allowed in Wrigley Field."
The Cubs then went on, without Billy Sianis or the goat, and lost that World Series Game 4 and there has never been another Cubs World Series appearance since then (of course, until 2016).
Maybe the Five Guys' Goat Was Allowed In. It Certainly Walked Far Enough To Deserve It. --RoadGoat
