Yea we all know a David Mandel but this one wrote for "SNL",  “Seinfeld”, wrote and directed “Curb” and “Veep”! Pretty, pretty good credits and he explains how it happened, what it's like working with Larry David, Jerry Seinfeld and Julia Louis-Dreyfus. There's a lot of advice for aspiring writers as well. And if you listen closely you can hear his son practicing his prayer for the matzoh.
