"Wouldn't it be funny if humans had to recharge, like cell phones?" We do. It's called sleeping. amirite?

You can use a cell phone while it's charging. I can use you while you're charging, but I think that qualifies as rape.

And eating. You can use someone while eating. Heck you can use yourself... Bad mental image

Clearly I needed a LOT of charging because I just slept for 16 and a half hours... :$
