Invisible Walls

Gosh, there's a huge deposit of lutetium over there! Private Gomez, go lug it back here, will you? Stop kidding around, Gomez, that mime impression isn't fooling anyone. The "invisible wall" gag is about as old as it gets, and it looks better when you're facing your audience, anyway. Move it, Gomez!

Gosh, he's doing a lot better at that mime thing. It's almost like he's feeling his way around a small maze, or something. Ah, here he comes back with that lutetium. About time, Private!
