Rosh Hashana was over and there was time until Yom Kippur, and Abie needed his tallis cleaned. He called his friend Max to ask what dry cleaner to take it to.

Max said, I always take my tallis to Moishe the dry cleaner on W 4th. He only charges $4.00

So Abie goes over to Moishes and finds that the ownership has changed. He asks the new owner, Mr Jones, if he meets the old prices. Mr. Jones assures him that he does. Three days later, Abie goes to get his tallis and is given a bill for $24.00.

He storms at Mr Jones. I thought you met Moishes prices?

I did, said Mr Jones, $4.00 for the tallis, and $20.00 to get all the knots out of the fringes!
