Hmmm, we got a slightly different one at work

where has the mouse gone?

Out of interest - where did this pic come from?

Guessing - it looks like maybe some museum but not sure where.

Im working on a power-plant as a engineer. We did some clean-up in a storageroom and found this alternative power-supply, somebody made long time ago. I dont know if it works, but at least i think it was funny....

I think you've found the answer to the oil shortage problem arentzen - it's registering 10 amps output with no apparent effort.

That's efficiency!!!!

Yes! I have to hurry up to register this invention. THE ETERNAL POWER SUPPLY

it's just that pesky 2nd law of thermodynamics getting in the way

Your just too clever by half Sd.

(..but do you understand too clever by half )
