but certainly NOT this:
Apparently in the town of Fenton, Michigan, an urn full of ashes appeared at the local Goodwill. The box it was in was labeled, appropriately (or inappropriately) "Grandma's Urn". Ten inches tall and weighing 10 pounds (that's a shit-ton of ashes), Goodwill Manager Allen Ryckman (not the actor playing Severus Snape in Harry Potter) says it is the #1 or #2 weirdest item ever received.

So remember, when selecting items to donate to Goodwill, make sure you don't give granny's remains away.
