Last year I was chatting to a radio producer and I mentioned that I write jokes, and that I was hoping to write more topical stuff possibly for others to use.
He suggested that I send him about 40 or so jokes on any particular subject and if any were good enough to be used he'd pay for them.
What's the etiquette on this. Can I now not use any of those jokes until I know which ones he wants? Am I free to send the same list of jokes to other people that have asked me to write topical stuff for them? If he reads one of my jokes and then very slightly rewords it, is that still my joke?
Advice from people who regularly do this stuff gratefully received.
