I'm going to fart at a funeral then nervously laugh
What do you like about farts?
I find the simple and plain truth of life is contained in a fart.
A funeral is a solemn occasion and people are grieving for their loved ones, so farting is not a good thing to do at the time. People will think that you are heartless.
Come on. Have some fun!
You shouldn't be having "fun" at the expense of the grieving during a funeral. Don't do this.
