One of my favorite TomSka videos (and I assure you, there are many) is Meanwhile, exploring the possibilities of various parallel universes occurring in one room. It’s one of those YouTube skit ideas that’s low budget, fast, and funny — and makes anyone watching yell out “Dammit! Why didn’t I think of that?!”
The sequel is just as good, and now? There’s a third!
Meanwhile, in a parallel universe, these stopped after the second video, so take the time to watch and appreciate what we have. Hoorah!
