An old Scottish builder

A tourist is backpacking through the highlands of Scotland, and he stops at a pub to get a drink. The only people in there are the bartender and an old man nursing a beer.
He orders a pint and they sit in silence for a while and suddenly the old man turns to him and says to him, "Ya see this bar? I built this bar with my bare hands. Found the finest wood in the county, gave it more love and care than my own child, but do they call me McGregor the bar builder? no... NO!"
He points out the window "You see that stone wall out there? I built that stone wall with my bare hands. Found every stone, placed them just so through the rain and the cold but do they call me McGregor the stone wall builder?... no... NO!"
Points out the other window, " You see that pier on the lake over there? I built that pier with my bare hands, drove the pilings against the tide and the sand plank by plank but do they call me McGregor the pier builder?... no... NO!... but ya fuck one goat..."
