"Dancing Strictly Forbidden" joke

Preparing for their religious wedding, a modern Orthodox Jewish couple met with their rabbi for counseling. Before leaving the meeting, the rabbi asked if they had any last minute questions.
"Rabbi," the man asked, "we realize that it is tradition for men to dance with men, and women to dance with women, at the reception, but we would like to ask for your permission to dance together."
"Most definitely not!" replied the rabbi. "It is immodest. Men and women always dance separately."
"Then I can't even dance with my wife after the ceremony?" asked the man.
"NO!" answered the rabbi. "It is strictly forbidden."
"Well, what about sex?" the man asked. "Is it permitted for us to finally have sex?"
"Oh, certainly," the rabbi said. "Sex is a mitzvah within marriage, to have children."
"What about different positions?" the man inquired.
"That's no problem," said the rabbi. ""It's a mitzvah."
"Even with the woman on top, or doggy style?" the man asked.
"Sure," answered the rabbi. "Go for it, afterall, it's a mitzvah."
"Can we even do it on the bed, with mirrors on the ceiling, a vibrator and a bottle of hot oil?" asked the man.
"You may indeed. It's all a mitzvah," the rabbi replied.
"What about doing it standing up?" asked the man.
"No! No!" the rabbi exclaimed. "Absolutely not! NEVER standing up!"
"Why not?" the confused man asked.
"That could lead to dancing!" the rabbi replied.
