Missionaries

My dad was LDS and he hated when the missionaries would come over. He devised a method that worked a lot of the time. He would introduce them to a new invention of his. This time it was the "Propcycle", a bicycle-powered by a propeller. One of the missionaries took a ride on it and the other asked my mom a question. Has Mr. Watson invented anything for you? Why yes he has, it was a solar clothes dryer. At this point, the missionary got wide-eyed and asked if Mr. Watson had any difficulties with it. My mom said yes, He had difficulty in getting the ends dug deep enough and at the right angle to allow for the strain of the lines. His eyes then spied the outside clothesline. My mom was great with the puns.
