You are given a plate of spaghetti and told to do the following: Pick up one end of a spaghetti noodle and tie it to another end of a noodle (randomly selecting each). Continue to do this until all the ends have been tied together. If there were originally N pieces of spaghetti, what is the expected number of loops of spaghetti you would form? A loop may consist of any number of pieces of spaghetti tied together, and the loops could be linked to one another.

Wow.
That is thought-provoking.
This is one case for which I am glad the solution details are not (yet) divulged. ;)

Nice puzzle also.
