You really don't have to come back. Really. Don't feel beholden to check back in on us. We'll be fine.
See ya, Ioo. Throw a coin in Trevi fountain for me. Make love to a passionate Italian woman for me. Cut a hole in the ice and go ice swimming with some fat russian bald guys for me. Plant a top-secret listening device in the Kremlin for me. Buy a nuclear warhead on the Russian black market for me.
Russian nukes used to be really cheap (for nukes) as well... For $60k, you could get yourself a nuke, and the boot of a car (with rest of car) to put it in.
