Food&Pants has always been the premiere website for all things Rachel Dratch. Well, that being said...
I met someone today with the last name "Dratch" - a young man with a pleasant demeanor and a zest for life. I asked him if by any chance he was related to Rachel Dratch, and as it turns out they're distant cousins. Unfortunately, he was unable to give very detailed information, as his side of the family is no longer on speaking terms with Rachel's side.
Anyway, that's it.
