My god, I thought I was going to split a gut at last night's episode. The prop makers outdid themselves unless they somehow had a version of the Time Machine in a warehouse somewhere.
I noticed it was two "new" writers to the show, I think. Maybe one of THEM had it and wrote a script around it. In any case, it was very funny.
And we actually got to see the inside of the elevator shaft!

I do remember that the original Time Machine prop was found in a junkyard and restored by an L.A. sf fan, who kept it for a number of years. This was back in the early 80's so I don't know what's happened to it since then. That was either the original or a very close reproduction.
The bit where Sheldon, Raj and Howard all speed up jerkily as the "Time Machine" goes through time had me roaring. Too funny.
And the end bit -- "Starving Morlocks." That's a hall costume just waiting to happen!
