In the comic strip "Barnaby" by Crockett Johnson, popular during W.W. II, the little boy's fairy godfather, Mr O'Malley (a vulgar Irishman with flimsy but functional wings) continually exclaims "Cushlamochree!" as a mere exclamation of surprise or dismay. I had no idea what it meant until, many years later, I had occasion to look up the better-preserved version in a poem by John Betjeman:

The roll of the railway made musing creative:
    I thought of the colleen I soon was to see
With her wiry black hair and grey eyes of the native,
    Sweet Moira McCavendish, acushla machree.
