Fun pop culture reference or .... copyright infringement?

Terrific, well-researched and well-written article by Will Ziebell on The Crafty Pint exploring the issues around the use of names and images of films, characters, confectionery, etc.  Not sure he mentioned song names, but the principles are the same.
This is well worth a read.
