I always think about a goose loose in the rain (Mr Forgetful)! But have to consider the spelling of choose by thinking of the past tense, chose. (Also, pronouncing noose and nose, is it that 'lose' is an exception to the rules of pronunciation in this case? Are there actually any rules?)
Then there are the following:- cough, tough, trough, chough, rough, bough, bought and taught! The only way to pronounce these properly must be to learn them. Oh isn't our language interesting (to a pedant)?
