Would you rather:

have a machine in your room that had an infinite alcohol flow. You can stick a glass on the tap, and it charges you 10p a go, and you get a pint of lager.

OR

a mythical beast, approximately 6ft tall, that is basically a big massive dog that you can ride places. You tell it to go round corners and speed up etc, but it can't do anything other than run, so no 'it could kill people'. Its a peaceful being, why can't you just accept that?
