Belligerent English thugs have been the Irish curse for centuries.

Colin Farrell mentioned he had a case of the Irish curse after drinking too much one night and taking a lady home

Dumbass: Hey, why are you wearing that golf cap?
Irish guy: It's a fooken Irish cap! Arsehole.
Dumbass: What, so you're Irish?
Irish guy: No shite!
Dumbass: You're suffering from the Irish curse. Am I right?
Irish guy: It's the Scottish curse, ye dumb fook!
Dumbass:There's a difference?
Irish guy: *sigh* I'd beat ye to death with me own dong but ye'd probably like it. *shoots the dumbass instead*

in early howard stern days, he said he suffers from the irish curse, and he was referring to his penis looking small after nights of drinking because he was unable to get an erection, pay attention to what he actually is refering to.

also, colin farrel explains in a tv interview that after a night of excessive drinking he suffered from the irish curse when he took a girl home, he obviously didnt mean that he has a small penis. also, he was born and raised in ireland, so i think he would know about the history of this kind of things.

"Yes, I suffer from the Irish Curse"--uttered by a guest on the Howard Stern show's episode about small penises.
