A little time ago a polling company was asking about the smartest inventions.
They got lots of very good answers. The telephone, computers, airplanes, Televisions, and so on. Well they got a hold of a DUchebag that said he had an IQ of 160 and that the smartest invention in all of history was the Coleman Cooler. Surprised at this answer, the pollster asked why. The self proclaimed super intelligent DUchebag replied "Well it keeps cold things cold AND it keeps hot thing hot." The pollster said "Yes it does but why is that so smart?" The self proclaimed genius of the DUmp snidely replied back "How do it know?"
