I would suggest pronouncing “pain killers” in a nice French accent (pan keelUHRZ) when telling the joke. Writing it down might not be necessary then.
ETA: not a native English speaker (nor French). Nor a dad. Also, I tried saying it out loud a few times, and it still misses something. I do see potential, but it might need someone better qualified to fix this completely.
