Winding up the tough guy

I was sitting at a bar one time, when I noticed that, next to me, an old drunk was hassling one of the biggest, toughest guys I'd ever seen.

The old guy was clearly blasted, and kept getting in the tough guy's face, say, "I fucked your mother."

Despite being huge and jacked, the tough guy just kept shrugging it off. The old guy laughed in the tough guy's face, saying it again. "Hey, I fucked your mother."

Then, the old man even poked him, and repeated himself, "No seriously, I fucked your mother."

At this point, finally, the tough guy had had enough. He grabbed the old man by his jacket and began to pull him out of the bar, yelling,

"That's it. We're going home, Dad. You're drunk."

Lee Raymond Dice

Born 15 Jul 1887; died 31 Jan 1977 at age 89.American zoologist, geneticist and ecologist who introduced biotic provinces to characterize areas of continuous ecological similarity in climate, soils, and topography. He investigated geographical and ecological distribution pertaining to plants and animals in fieldwork throughout the Southwest and Mexico in the 1920s and 30s. When he found C. Hart Merriam's idea of life zones to be inadequate for modeling distribution patterns, he developed his concept of biotic provinces. Dice demonstrated their application in his book, The Biotic Provinces of North America (1943). He is also known for his derivation of the Dice index, a similarity coefficient used to measure degree of association between biotic samples.«
