I see there is a lot about americans here......
..well i won't disappoint. A work collegue of mine has a friend who works as an Air Stewardess for British Airways, who regulary do flights from Uk to American for those who didn't know.

Anyway on a flight from one to the other (not sure which but over the Atlantic) an American gentleman asks for a cup of Coffee with cream.

Unfortunately they had run out of cream so the gent was asked if milk would suffice to which he pleasantly replied yes. The Stewardess hands the gent his coffee and two of those little tubs of milk. The worldly American studies the milk tub looking awfully confused and after a brief moment, turns to the stewardess asks, 'What kind of animal is a UHT !?'
