As far as your original problem is concerned, head down to Niagara Falls and set up an elaborate sketch about how you're trying to convince him not to commit suicide. Make sure lots of people see (not difficult), but not too closely (more difficult). Depending on the state of decomposition, you may need to cover him from head to foot, so pick a cold day. You might want to actually stage it below the falls, as it is more likely that they will never recover the body. The sketch ends, of course, with you making an heroic but ultimately unsuccessful attempt to save his life.

Hide him in your belly.

Just call The Wolf.

Yes, it's real, and I actually have killed my roommate using paperclip, some cellophane and nearly full box of dental floss. That's also why I'm asking for help in hiding a body on an Internet forum.

After you hide the body, okay?

Try combining the objects in your inventory. If that fails, try interacting with them; maybe you'll get something you can use.

Where do idiots like you come from? Is there a breeding farm where they use the semen of Dr. Demento?

Maybe you didn't see the blindingly obvious sarcasm in my last reply to you. Anyone with half a brain would know better.

Can we have some classier trolls in this forum, please? The one we have right now is broken and doesn't come with a travel adapter.

You're right, it is for publicity. I'm trying to sell Johnson & Johnson's REACH® Waxed Dental Floss. Are you getting tired of all those sticky and rough brands of dental floss from the competition? Thanks to REACH® Waxed Dental Floss, you no longer have to worry about that! Simply tear off some floss, pop it into your teeth and slide it back and forth.
