"Sabbath Violator. Morris and Lenny are s..." joke

Sabbath Violator.
Morris and Lenny are strolling home from shul one Saturday morning. Suddenly a cab speeds past, and their friend, Irving, is running frantically behind it, flailing his arms wildly.
"Well," said Lenny, "I never imagined our good friend Irving was a Sabbath violator! Look at him running for that taxi."
"Wait a minute," Morris replied. "Didn`t you read that book I lent you, `The Other Side of the Story`, about the command to judge other people favourably? I`ll bet we can think of hundreds of excuses for Irving`s behaviour."
"Yeah, like what?"
"Maybe he`s sick and needs to go to the hospital."
"Come on! He was running 60 miles an hour after that cab - he`s healthier than Arnold Schwartzeneger."
"Well, maybe his wife`s having a baby."
"She had one last week."
"Well, maybe he needs to visit her in the hospital."
"She`s home."
"Well, maybe he`s running to the hospital to get a doctor."
"He is a doctor."
"Well, maybe he need supplies from the hospital."
"The hospital is a three minute walk in the opposite direction."
"Well, maybe he forgot that it`s Shabbos!"
"Of course he knows it`s Shabbos. Didn`t you see his tie? It was his paisley beige 100% silk Gucci tie from Italy. He never wears it during the week."
"Wow, you`re a really observant! I didn`t even notice he was wearing a tie."
"How could you not notice? Didn`t you see how it was caught on the back fender of the taxi?"
