One day a man decided to go for a walk in the park. He put on his walking shoes and grabbed his jacket and took off walking to the park. As he was walking through the park, he came upon a heavy set woman sitting on a park bench naked eating pizza with her legs spread wide open. The guy was shocked by what he saw. He approached the woman and asked, "mam? Why are you sitting on a park bench naked eating pizza with your legs spread?" The woman instantly replies in a deep smokers voice, " It keeps the flies off the pizza". The man not knowing what to say continued on his walk.
