Sam and Janet evening, you will meet a stranger...
Sorry, but it works better as: "Sam and Janet Evening, you will ..." Making all the three puns part of their names extends the joke.
By the way, there are (is) certain writers who only post dirty jokes.
Whenever someone tells me they can't write a thing, I always think 'they just haven't found their story yet'. When I was young, I had no desire to write, and thus never studies English in college. However, most authors here are older individuals who came to writing while reading someone else's stories, and thinking, 'I can do better than this'.
You don't need to be a creative genius. All you need is to tell a particular story better, and it can be better writing, better story, interesting twists, different perspectives, alternate focus.
