A few years back on sapfans, someone was an end contestant for the Darwin Awards competition for asking about BAPIs to change the expiry date when reprinting labels.
I believe the question was in November even, but was traced back to a yogurt manufacturer and not chocolates.
Darwin awards on SCN is not very exciting as we reject the question in the first place. Perhaps we should let a few through just for fun.. ;-)
In the security forum I am aware of one thread which got very close -> http://scn.sap.com/thread/3636972
