Rabbi Simcha Weinstein grew up in England. As a short fellow, he waited for his growth spurt. That never happened, so to avoid the anti-Semitism he confronted, he became funny. He later turned that humour into his own stand-up and wrote a book describing how Jewish humour has changed in the 21st century and how comedians like Sacha Baron Cohen, Sarah Silverman and Jon Stewart now use the old taboos to get lots of laughs.
