Ready for another?
Okay,
In the arctic a Dr. Whozawhatzit is studying temperature in relation to ice decay. He sends out a student to check the official temperature outside and radio back in because he is the Doctor and shouldn't have to walk a mile in the cold and dark.
The student radios back stating that it is negative forty degrees and states, "I forgot to check which setting I had on the thermometer, Celcius or Farenheit do I have to go back and redo it?"
The doctor, a very accurate and fastidious person replies, "No, don't bother, just get back in here!"
Why would the normally accurate doctor not care if he went back to recheck the data?
I don't like that one. It could have been in degrees kelvin.
