Change Isn’t Easy
Sol Goldberg was fed up already with all the anti-Semitism and went to the priest and said he wanted to convert, and the priest said, "Okay, on one condition: you don't eat fish on Friday night."
Sol said, "No problem" and the priest sprinkled some water on him from a bottle on his desk and said, 3 times, "You're not a Jew, you're a goy, you're not a Jew, you're a goy!" and Sol went home happily.
Friday night arrived and the priest wanted to see if Sol was keeping his word so he went over and looked in the window and he saw Sol eating a fish! And not some little gefilte, mind you, but a whole salmon! So the priest went into the house and said, "Why did you lie to me? You said you wouldn't eat fish on Friday night!”
Sol replied, "Mr. Priest, it's not a fish, it's a chicken."
"What do you mean a chicken?! I see it's a fish," replied the priest.
"Ah", said Sol. "You are right. It was a fish, but I learned from you and now it's a chicken."
"Learned from me?" asked the priest.
"Yes. I sprinkled some water on him three times and said, ‘You're not a fish, you're a chicken. You're not a fish’”…
