Ooh, just thought of another one.
My ex-wife (she may well feature again before the end of the week) had a friend called Roz.

And we had a marriage guidance counsellor called Ross.

Despite me explaining many times that one was pronounced "Ross" and the other "Roz", she used to pronounce Roz as "Ross" and Ross and "Roz". But then sometimes she'd say them right.

Consequently I never knew if we were going out for a drink or for another bout of counselling.
