During a smoke break some co-workers and I began talking about ciggarettes. We discussed the number of stripes on a Camel Light. Then the toxicity of nicotine (it is more toxic than stricnine or arsenic I've been told). Then it was stated that the ocean liner Queen [sic] burns 1 gallon of deisel for every 6 inches it travels. Next were the crickets. Someone suggested that if you counted the number of chirps over 15 seconds and added the number 40 the result is the current air temperature (I don't know if that is F or C).
So. What is the most useless piece of knowledge that YOU possess?
