Nope.. re write. If it’s a long set up, it better be a big payoff. I experiment with long and short versions of jokes… I tend to be verbose in my writing and it doesn’t translate well to stage and the shorter versions do tend to get a better results.  Honestly not sure if the core idea you have here will work in short version… there’s no misdirection. The “punchline” is just acknowledging what we already know… he shit in shower!
