BSD, what makes the Sem on the bus joke so funny for me right now is that I am sitting in the hospital waiting for my friend to deliver her first baby. So that was quite funny for me. Thanks, it broke up the tension for me.
As far as the Tatta who is nisht in zein hoizen, I think that is either very common or you must know us, because my daughter said that about 25 years ago to the meshulachim at the front door.
