I just had a great idea. It's goddamn brilliant.
What if there was a company who provided "Coma Services" for your family pets? That would be awesome. And convenient! Say you wanna take a trip to visit your estranged former European lover, but Helmut Von Sczoolzefub doesn't allow pets? Well, you take yer yappy puppy on down to the local coma emporium, put him to sleep for the desired duration, and there he his, alive and well for your return.
And holy shit... this could be even better for those annoying old people you're are legally obligated to look after. Don't wanna take ancient Uncle Fred to Hawaii? Well sir, you just pack the old bastard up and take him on down to the coma place. And if the lonely, widowed asshole dies? They give you the next coma free.
