[Tutor] I can't believe this needs to be this complex

I'm pretty new to Python's dictionaries, but I had a need for a 
function that would find the values in a dict that have more than one 
key each. It took me several hours to write. See 
<http://py77.python.pastebin.com/f397582d8>. Seems to do the job, 
both with the example shown, and with the dict of colors at 

But I can't believe the function needs to be so complex. And also, I 
suppose I've reinvented the wheel (again). Please instruct me.

My apologies in advance to Kent for not using a single list comprehension.
