From a foreigner’s PoV:
English – drink warm, stale beer, eat baked beans, wear 3 Lions shirt
Welsh – Giggs and sheep
Scottish – talk funny (like Germans), play stoopid instruments, all are ginger
Northern Irish – Irish who are English.
almost.
After conducting an in-depth survey of lots of foreign types, I can confirm that it actually goes as follows:
English – drink warm, stale beer, eat baked beans, wear 3 Lions shirt
Welsh – Inbred leek-crunching cottage-burning yokels who would be better off if somebody just nuked the entire ‘country’
Scottish – talk funny (like Germans), play stoopid instruments, all are ginger
Northern Irish – Irish who are English.
