One little idiosyncrasy he had was when he had to shoot left handed. If you ever saw him shoot a shot lefty you never forgot it. He would lay his right hand down on the table palm side up. Then he would make a circular bridge with his thumb and index finger. It looked so strange, but it worked for him. I never knew anyone else to try this bridge. It was uniquely Lassiter's.
I've seen a picture of this very scene somewhere. I know I have a coupe of Billiards Digests, one with an article that I've found called "A Weary Wimpy Looks Back". I have another with an interview with Wimpy and Allan Hopkins which describes Lassiter's 9 Ball philosophy. I'm trying to find that one now.
