Best show of the new season. This was a big surprise. Looked to be a dumb idea but its quite funny. What's not to like about this Halloween episode. 4 guys each dressed up as the Flash. Then Leonard dresses up as Frodo and explains the difference between a elf and a hobbit. And of course there was Sheldon dressed as the "Doppler Effect". Priceless. So far they have had 2 of the cast members from the old Roseanne show on. I wonder how soon before John Goodman will be a guest.
