I like to imagine that somewhere in Silicon Valley, there is a sandwich shop which caters to nerds. They send out special deals via RSS feed. Naturally, they call this the PubsubHubbub Sub Club.
Based on the special they're running, they keep extra ingredients handy to satisfy demand. Each morning, they must fill the PubsubHubbub Sub Club Grub Tub.
At the end of the day, they clean it out and wash it thoroughly. They do this, of course, using the PubsubHubbub Sub Club Grub Tub Scrub Nub.
