If your dad is going on a buisness trip on a plane this is a good one to do.
Do that shaving cream thing where you freeze a whole big can of shaving cream and saw the top off and have it ready.
Soon as you find his bag or bags put it in there with his cloths and all and when it thaws it will get everywhere and mess up all his stuff.
Hopefully he is going on a trip far away because if he is this is gonna be good, because he will have no cloths
He will be away from his bagson the plane when it thaws so he will not hear or see it explode so when he gets to his hotel and gets his suit out for his meeting that crap will be all over it
