For those of you who haven't seen the movie, Tim Allen's character is on an alien planet, about to get killed by a rock monster, while the rest of his crewmates have returned to the ship. They want to rescue him by teleporting him up to the ship, but they've never used the equipment before. So they decide to see what happens if they teleport the pig-lizard animal that was used as bait for the rock monster...
[Fred has tested the "digital conveyor" teleportation device on a pig-lizard that was chasing Jason Nesmith, but the pig-lizard has been horribly mutilated by the process.]
Jason Nesmith: [over the comm] What was that?
Alexander Dane: Uh, nothing.
Jason Nesmith: I heard some squealing or something.
Gwen DeMarco: No, everything is fine.
Teb: [cheerfully] But the animal is inside out.
[Gwen quickly tries to cover Teb's mouth]
Jason Nesmith: I heard that! It got turned inside out?
[The pig-lizard bursts, spattering the area with gore. Some of it lands on Teb.]
Teb: [unphased] And it exploded...
Jason Nesmith: Did I just hear that the animal turned inside out and then exploded!?!
Gwen DeMarco: [distressed] Um... hold, please.
So I've been working on a kinematic model for several weeks now. It's supposed to be a sales demo for a potential customer. They provided me with CAD files and information on their spring properties, etc. For some reason, I just haven't been able to get realistic results from the model.
After several rounds of back-and-forth with the Design Engineer, I finally learn that they're in the middle of changing vendors, and the information that I've been given is a mish-mash of data from the "old" design and the "new" design. So I've spent most of today rebuilding the model. When I tried to delete one of the "old" components and replace it with the "new" component, the model turned inside out.
And then it exploded.
And of course, as I was in the middle of making the change, I thought to myself, "I should really make a back-up file, in case this doesn't work correctly." The problem is that I had that thought just one minute too late. So I lost several hours worth of work, and now I get to do it all over again.
And it's my own damn fault.
