Sounds Fishy

All those teachers who complain that their students frequently doodle may find some solace in the Gemara (Gittin 36a). The Gemara says that Rav would frequently draw a picture of a fish. As it will become clear from the commentators, this was not just some random scribble that someone with a good imagination could perceive as a fish. Rav was actually able to draw a mean picture of a fish. If the Taz had his way, Rav’s pictures of fish would have far-reaching implications; serious doodlers and wouldbe artists would have fewer restrictions on their practice. Alas, it wasn’t to be. It seems as if the Shach prevailed, and the import of Rav’s fish drawings will be relegated to the laws of witnesses.
On one point all agree: if Rav drew a fish, then drawing a fish must be permitted. Before this article sounds too fishy, it must be explained why exactly Rav would commonly draw a fish. The Gemara says that Rav drew a fish in lieu of his signature on legal documents. His practice became so well known that it was common knowledge that if there was a picture of a fish in place of a witness’s signature, one would assume that Rav signed it.
