"Not What it Seems..." joke

There was a Jewish woman, and she had three sons, who were in their twenties. They were all at the point of getting married, and the oldest son was the first to get engaged. He confronted his mother with the good news.
"Mom- I just got engaged to the best woman in the world!"
"That's great Joel, is she a nice Jewish girl?"
"Well, she's nice, but she isn't Jewish.
"Oy. Okay son, tell me her name."
"Her name is Yummigucci. She's Japanese."
"Well, son, as long as you are happy, I wish you the best."
So her first son got married. Then her second oldest son came along telling her he was engaged, also.
"Mom! I'm engaged!"
"Wow, Eddy, I'm pleased for you! Is she a nice Jewish girl?
"Well, not exactly, she's Greek Orthodox."
"What's her name?"
"Krocapocalipessisi.
"Well, as long as she is good to you, I am happy for you."
So her second son got married. Then her youngest son came along telling her he was engaged.
"Oh, Lenny! That's great! What's her name?"
"Goldberg."
she almost fainted in joy.
"Oh, son! i'm so so so proud of you! i can't wait to meet her! What's her first name?"
"Whoopi."
