I've deleted the post. Telling an "old joke" is one thing. Telling other people's jokes as if they were your own is something else entirely -- as is solely telling previously-written jokes all the time as your voice and giving no indication that they aren't yours. As a professional writer I take these things seriously. To professional writers, it's among the most-serious thing. At best it's foolishly thoughtless. At worst it's plagiarism.
Sorry for the raves. They've been taken down, here and on Facebook. And thanks to Ed.
