Who's Who

Don't you just hate it when you record a perfectly good episode of a podcast, edit it, and then go out for a walk with your dogs while it exports to MP3, only to return and foget all about it for the next five days? ... What, that's never happened to you? Oh. Well, it happened to me, hence this episode being released on a Sunday rather than a Wednesday. In other news, alternate reality stories continue to be "Oh, isn't that highly relevant person/thing/device quirky?" rather than "This universe is the same as the one we're from, except pig flatulence is now visible to the human eye... That is also the only difference." Why don't they ever end up in that universe? Or the universe that is the same as theirs because the differentiating point happens in the future? Or how about they travel to an alternate universe where cockroaches can hear infrared radiation .. and everything else is exactly the same? On that note, why don't they ever end up in a parallel universe where the Earth was never formed
