an old man with missing teeth may come up to you telling you stories of his earlier years as a stuntman and how he can get into any movie he wants. ( you dont believe him). and then he'll proceed to tell you about the young woman that has fallen in love with him and how he cant morally be with her as he is about 80 years and she is in her 20s. when you say goodbye you put up your fist for a bump and he will grab your fist as if it were a hand shake.
