Okay it's an email joke, so forgive me. I can't resist:
The year is 2012 and the United States of America has recently elected the first woman as well as the first Jewish president, Susan Goldfarb.
She calls up her mother a few weeks after election day and says, "So, Mom, I assume you will be coming to my inauguration?"
"I don't think so. It's a ten hour drive, your father isn't as young as he used to be, and my gout is acting up again."
"Don't worry about it Mom, I'll send Air Force One to pick you up and take you home. And a limousine will pick you up at your door."
"I don't know. Everybody will be so fancy-schmantzy, what on earth would I wear?"
"Oh Mom" replies Susan, "I'll make sure you have a wonderful gown custom-made by the best designer in New York."
"Honey," Mom complains, "you know I can't eat those rich foods you and your friends like to eat."
The President-to-be responds, "Don't worry Mom. The entire affair is going to be handled by the best caterer in New York, kosher all the way.
Mom, I really want you to come."
So Mom reluctantly agrees and on January 21, 2013, Susan Goldfarb is being sworn in as President of the United States of America.
In the front row sits the new president's mother, who leans over to a senator sitting next to her.
"You see that woman over there with her hand on the Bible, becoming President of the United States?"
The Senator whispers back, "Yes I do."
Says Mom proudly, "Her brother's a doctor."
