Beaucoup:

If pronounced Boh-kew or Boh-koo, with a slight pause in between them, sounds like the word is being split into Beau Cou, which means beautiful neck.

If pronounced Bohkou, quickly, with no gap, comes across as Beaucoup. I gotta admit tho, I had to really think about that one, it's a very subtle difference.

(don't mean to sound condescending, I'm sure you know how to pronounce it now, you just got me interested with your comment :P)
