This is AMERUKA! We don't use no stinkin' SI Units in AMERUKA!
We are red-blooded Bible-Totin' red white and blue people that use FEET, and INCHES, like the Lord intended normal people to use. Millimeters, PAH!, that what drug dealers use when rolling reefers!
Here in Ameruka SI unites is an abbreviation for SISSY man ... the kind of man that will watch Star Trek and yell for Captain Kirk to set his Phaser on STUN!
REAL MEN don't use STUN. and REAL MEN don't use millimeters !
