TV Ate My Dinner: Time Travel!

Time Travel!  The boys discuss time-bending classics like Quantum Leap and Back to the Future, the temporal antics of the many Star Trek incarnations, and the many faces of Doctor Who.  What are the real life applications of time travel and alternate realities?  Did Napolean Dynamite get it right when it comes to strapping yourself to a car battery and looking for a vortex?  And what does Predator 2 have to do with any of this?  Somewhere in all this there is also time for a little discussion of the new Knight Rider movie.
