It really is. Ruining a beautiful pint like that, its a terrible thing to see.

A lot of Irish Americans drink a Guinness, poured on top of an ale or lager (not quite such blasphemy!), but strangely they call it a 'Black and Tan'. Presumably something got lost in translation there, as I'm pretty sure ordering a Black and Tan in most pubs in the Republic, would be liable to get you glassed!

No thats a thing here in Ireland too. Normally with smithwicks ale its called a black and tan or in some parts a pint of "special". While I am a big fan of the guinness I have had special a few times in the past and it works fairly nicely.

I never thought of that before, but it actually makes a whole lot of sense - they knock you out! Awesome, thank you. New bit of etymology learned!
