MacGregor the builder

A man walks into a bar, takes a seat and orders a pint. He gets his drink and takes a sip. The man sitting next to him looks him in the eye and says "Eyyy laddie, you see this bar here? I built it with me own two hands. MacGregor the bar builder they called me." The man falls silent for a while, then perks up again and turns to his neighboring man and says "Eyy laddie! You didn't forget about me? You see that wall outside, the one made of solid stone. I build that with me own two hands. MacGregor the Wall Builder they called me after that." Silence falls again. The old man once again turns and says "Do you see that pier out there lad? I designed and helped build it - 3 men died during its construction. MacGregor the Pier Builder they called me after that". But you fuck one goat...
