I had the longest, most pointless exchange with the dumbest person on this earth. This one out-dumbed the last dum-dum by about 5 points on the dum-dum scale.
Remember, these people are driving on your roads, cooking your dinner and handling your money. Be warned.
Sad to think of all the cute animals killed in traffic but these people, thanks to modern healthcare, will spread Teh Dumb forever.
