 Sid and Al were sitting in a Chinese restaurant. ""Sid,"" asked Al, ""are there any Jews in China?"" 

 ""I don't know,"" Sid replied. ""Why don't we ask the waiter?"" 

 When the waiter came by, Al asked him, ""Are there any Chinese Jews?"" 

 ""I don't know sir, let me ask,"" the waiter replied, and he went into the kitchen. He returned in a few minutes and said, ""No, sir. No, Chinese Jews."" 

 ""Are you sure?"" Al asked. 

 ""I will check again, sir,"" the waiter replied and went back to the kitchen. While he was still gone, Sid said, ""I cannot believe there are no Jews in China. Our people are scattered everywhere."" 

 When the waiter returned he said, ""Sir, no Chinese Jews."" 

 ""Are you really sure?"" Al asked again. 

 ""I cannot believe there are no Chinese Jews."" 

 ""Sir, I ask everyone,"" the waiter replied exasperated. ""We have Orange Jews, Prune Jews, Tomato Jews and Grape Jews, but we have no Chinese Jews."""
