A groaner

An Englishman, Scotsman & Irishman are in hospital recovering from serious surgery.

For conversation’s sake the Englishman says:

“What do you think is the best thing ever invented?” ” I think it’s the Pacemaker, because if it wasn’t for the Pacemaker it’d be curtains for me”.

Scotsman says: “Aye, The Pacemaker, ‘cos I had heart disease and if it wasn’t for the Pacemaker, it’d be curtains for me , too”.

The Irishman says: “Venetian blinds”.

Puzzled consternation from the Englishman & Scotsman. “Why???”

“Because if it wasn’t for them it’d be curtains for everyone”.
