It's wrong to sniff your own farts.
Martin is in bed beside Mary, his spouse, trying to fall asleep when he lets off a long and brutal fart.
Martin wants to take a deep breath.
Martin slips out of bed and goes to the window to inhale a breath of fresh air.
Martin throws his head under the covers and takes an inordinately long and deep inhale of his impossibly pungent fart.
Mary continues to sleep peacefully and wakes up rested and happy.
Mary notices Martin delighting himself in the glory of his fart and recoils in horror, jumping out of bed.
