Get a plastic bag and stick to her ass whenever she farts. Release to her face then I am sure she would do it again in front of you. Just try it.
But what happens if she suffocate and dies, wouldn't you get in deep shit for it??? -roflyawn-roflyawn-roflyawn-roflyawn
1) that is not Jackass enough!!! 2) you just might as well put the plastic bag over her head and let her die like that
