The enemy is anybody who's going to get you killed, no matter which side he is on.

O Paddy dear, an’ did ye hear the news that’s goin’ round?
The shamrock is by law forbid to grow on Irish ground!
No more St. Patrick’s Day we’ll keep, his color can’t be seen,
For there’s a cruel law agin the wearin’ o’ the Green!

For they’re hangin’ men an’ women there for wearin’ o’ the Green.

Gentlemen, you can’t fight in here. This is the War Room!

No taxation without representation.
