dog head
a dog head is a very good idea, but it would be difficult to pack it....maybe try the dogs tongue, and eyes, along with some stanky old bacon grease.........be sure to put a cd jewel case inside the package, so it feels like a cd. you've got the right idea though.
Some other things that are equally as disturbing are.
1. A used tampon
2. that clear jelly shit from inside a can of spam.
3. a blunt with ajax in it. (he may not know where it came from, but if he's a true weed head, he'll smoke it anyway.
4. bleach & cat piss............
