on LOVE, part three

If anyone can tell me the story or play or something where the hero is hopelessly in love, but he sucks at talking, and he has his friend hide and give him words to say, and the hero ends up wooing the girl using his friends words, and then eventually the girl realizes it isn’t the hero she loves, but the hero’s friend, it would be AWESOME.  It has been bugging me all week.  I may have some of the details wrong, which is probably why i couldn’t find it on google.
