It's funny, I never thought about the Dean using Jewish-isms thing as anything other than "a lot of the writers are Jewish."
That's the Doylist response! Watsonian's more fun!
John's parents could have had a mixed marriage, and maybe Dean has dim memories of Passover over at his Grandmother's place (but she died before Sam was born, so those memories are really dim). Bobby could *totally* be Jewish! (Actually, this seems fairly likely, for a Watsonian explanation.)
"Singer" is indeed a Jewish surname. I'll go along with Bobby being one of my people. :-)

My exact thought process was, "Or one of the hunters they saw a lot as kids was Jewish! Hey... Bobby's last name is Singer!"
LOL, it's crossed my mind on more than one occasion, P.M. It would totally set my heartstrings a-zinging if canon reveals Bobby to be a Member of the Tribe. I do a mean happy dance.
