Laughter heard around the world

So, I finally called my Dad in the Dominican Republic since getting on the plane back to the US in August. Erm, August 15 to be exact. Meanwhile, I broke it to Dad that I was decidedly converting to Judaism after all. Dad laughed. In fact, he couldn't stop laughing until the conversation was over. Of course, I made it worse by mentioning that his grandchildren were going to be Jewish. It wasn't a mean laugh, I think my Dad may have gone into shock.
