I was in Scotland when...

I was in Scotland, when I walk into a pub with only one man in it. I pull up a chair as he slides me a beer and I ask him why he's all alone. He answers,
"You see that barn out the window? I built that barn all by myself with me bare hands! But do they call me McGregor: The Barn Builder? FUCK NO!" He slams his pint on the bar loudly, and points out the other window.
"Y'see that bridge out there? I built that all by myself, stone by stone with me bare hands! But do they call me McGregor: The Bridge Builder? FUCK NO!" He slams his pint again.
"This very bar, I built it timber by timber with me bare hands but do they call me McGregor: The Bar Builder? FUCK NO!" He slams his pint one last time and cradles his head in his hands.

"But ya fuck one goat..."
