A scientist is sat at the bar when a scruffy hobo sits down next to him... ""Hey buddy, are you that scientist feller?"" ""... Yes I am. Is there something I can do for you?"" The hobo pulls something out of his pocket. ""I've found this marvelous material that's tough like plastic, stretchy like rubber and sticky like glue."" He hands it to the scientist. ""Why, yes!"" says the scientist ""This is quite a remarkable material. Wherever did you find it?"" ""My nose.""
