in my job, rhyming is essential

Martin, reading over my shoulder: "Welcome to the (comapny name/product name) bonanza." Bonanza?
Me: Its just a filler. Don’t you want to write me some marketing fluff to go in there?
Martin: No, I think you’ve got enough material to go on.
Me: OK, but can I still use the word bonanza?
Martin: No. (pause) It doesn’t rhyme with anything.
