Lemonade stand

B, with his father's help, set up a lemonade stand on the boulevard in front of their house. A jar filled with homemade lemonade and glasses sat on a table, next to a large sign: all B had to do was to attract potential customers. He took his job very seriously. He carried the sign and waved it at passing cars, yelling, "Fresh lemonade! Get your fresh lemonade!" A few minutes into this display, the next door neighbour came out. B hurried toward him, yelling, "Did you want to buy some lemonade?" B's father, whose relationship with the neighbour is tenuous at best, whispered, "Don't talk to him: he's crazy!" B stopped moving and turned to his father reprovingly, and in a VERY loud voice, "Dad! Even crazy people drink lemonade."
