-	You have a painting on a string. \par
-	Hang the painting on two nails so that if either is removed, the painting falls. \par

-	You may detach the string as you hang the painting, but it must be re-attached once you're done.
-
-	\note{The solution to this problem isn't a \say{think outside the box} trick, it's a clever wrapping of the string.}
