1st scientist: "This morning, on my way in, a police officer pulled me over for running a red light. I thought I would try talking my way out of the ticket by explaining that the light wavelength had shortened as I approached the traffic signal and the blue-shift made the red light appear purple which I mistook for a green signal to proceed through the intersection."
2nd scientist: "And that argument was successful?"
1st scientist: "Yes, it was, he did not give me a ticket for running the red light. However, he did give me a ticket for speeding, instead."
