I wish that I knew what to get the Morlocks living in my basement for a housewarming gift....
Granted. You realise that Eloi meat would be the traditional gift, and through great expense [lucky you won that lottery] develop a time machine and finance a safari to capture a few, which is reasonably easy. Unfortunately when you go to deliver it they mistake you for one of the Eloi, and you are eaten. On the upside, they think your body was an excellent housewarming gift.
I wish I was a budgie, with a nice owner.
