Mac is a well-known con-man and drifter, known for his winning ways with cards and women.
He is famous for real estate swindles, including that famous day when he sold Mortimer Mills, governor of our beautiful territory of Texico, "prime, rich, well-watered ranch land" that turned out to be the river bottom of the Rio Grande.
It ain't that he's never been caught, but he's a slippery one and can slip out of a jail as quick as Doc Loopy can yank a tooth!
Of late he's been seen in the company of Sweet Mary, reputed to be his syrupy sister. He is suspected to have had dealings with the late O'Blatherskite.
