Make mine a lovely Harp

Overheard by someone sitting near me at McCourt's before they shut down:

"I don't really like Guinness. I honestly wish I did. I mean, to be Irish, even half-Irish by marriage, and not like t' black stuff—well, it's a bit of a social handicap, innit? But t' truth is, if you give me t' choice between a Guinness and a pint o' horse piss—well, I'm goin' t' have t' seriously consider t' age and condition of t' horse."
