It’s quite clear from this story that Murphy was not a true Irishman.
An Irishman would have drawn a picture of a pint of ale.
an englishman, a scotsman and an irishman sit down in a pub and each order a pint of bitters. unfortunately each pint has a fly in it.
the englishman pushes his pint back, and demands a fresh one without a fly.
the scotsman removes the fly and proceeds to drink his pint.
the irishman pulls the fly out, hits it and screams, “spit it out ye wee bastard!!”
