Trivial You can teleport boxes by implanting them into bodies.

[The Grim Sleeper]

Reproduce:

1. Get a box (say a mechanical toolbox)
   
2. Use surgery to implant the box into your own body. Make sure you sew the the box securely into your chest cavity with the suture.
   
3. Fart the toolbox out and give it to somebody to put items into.
   
4. Travel a long way away
   
5. Use surgery to extract the implanted box, pulling it back though space-time, into your ass, and out off your body via your chest.
   

Doing this without securing the box also produces odd behaviour: when farting the box out, it appears both on the floor and in your hand or can be teleported. Its weird.
