"Just start talking about your vagina. They all leave."
In our case it went something like this. Laurie and me are the ones freaking out about how much work we need to get done in a very short amount of time:
Barbara - "And I used such and such a sauce on the fish..."
Laurie - "I think I'm going to start doing vaginal exercises."
Me (pointing at our work on the computer) - "That's a great idea! We can do that WHILE we work!"
Laurie - "You're supposed to stop your urine midstream."
Me - "You don't have to have real urine. We can type and pretend to be stopping our urine. It's still vaginal exercise."
Barbara (waving as she walks out the door) - "Ok. See you guys!"
