R.I.P. to your patient OP.

You must certainly have some extremely poisonous gas!

He who smelt it died

OP ACCIDENTALLY let one rip. For all we know, he/she was moving the client for a bath or something like that. In that case, a simple, "Excuse me" was sufficient. It's definitely a coincidence that the client died shortly thereafter but OP is blaming themself (a little) and did so through a little joke. If they said that at work, they would have been in trouble so using an anonymous outlet (here) is reasonable. It would be nearly impossible to track down exactly who the OP is and who the deceased is. Sometimes, especially people who work in a field where death isn't uncommon, they need to make light of it in order to deal with it.

You cut the cheese and he died? He must be lactose intolerant... that was a horrible joke. I shall hide in a dark hole now

The last memory of the patient was you farting.

I think not! Its called chemical warfare!

We really need a "bullshit" button.

Stop with those burritos man!

The sound probably scared them...Died of a heart attack.
