The engagement ring hidden in the balloon

I read an interesting story about someone who proposed to his wife in a hotel room filled with balloons.  When she said yes, he told her that she had to figure out which balloon was hiding the ring.  So, she started popping all of the balloons to find the engagement ring.  She made so much noise that the manager called up to the room and asked them to keep it down.  The full story is here.  Do you have any creative proposal stories to share?
