You know you're from America when and you are too busy exercising your free speech, partying with the most beautiful women on the planet, enjoying the world's greatest economy, cheering on the greatest warriors and Islamofascist-destroyers to ever live, watching the greatest movies ever made (even if lately they suck, they suck in a massive way no other country's film industry could ever suck even if they tried), and defending the greatest world leader alive that you can only laugh when the residents of all those other nations think you've even got the time to care that they called you dumbass. :) 
My grandparents were all from Ireland, btw, so no hard feelings--they were four very intelligent people. Obviously--they came here! :D :D :D :D
 
You know you are from Ireland when you can tell a verbose American to kiss yer arse! ;-) 
 No hard feelings :-Dx4! *LOL*
