What is it with Americans and their butchery of basic English semantics and pronunciation?
It's "I couldn't care less", not "I could care less." Think about it logically for a second or two and you'll find that the latter makes no sense at all.
Also, don't say "Without further a-due". It's "ado", people. Ah-doo, not a-due! Ever heard of that Shakespeare play?
And while we're on the subject:
Coup de grâce is pronounced "Coo-duh-grass", not "Coo-duh-grah." French may sometimes be confusing in terms of pronunciation, but -ce endings are never silent. Vide e.g. fem. name Alice.
