There was once a test to evaluate who was completely mad ,down town in mental institution in jo 'berg .they painted a door's image on a white wall & told a team of 21 madmen to go forth & open the door .the doctors stood a loof so as to analyze these guys .as others struggled to open the door ,they noticed one of them was watching the others. doctors knew this was a straight person .so they asked him why he aint opening the door .he pulled out a pair of his own keys from his pockets then looked at the docs
