A man goes to a doctor because he's been feeling really ill. The doctor runs some tests and comes back with a diagnosis: he has a rare condition that causes him to fart constantly. The doctor explains that there is no cure, but recommends a special diet that might help control the symptoms.
The man follows the diet religiously, but no matter what he eats, he just can't stop farting. He's so embarrassed that he starts avoiding social situations and eventually loses all his friends.
One day, he's at a bar and feeling particularly down about his situation when he sees a beautiful woman sitting at the bar. Feeling bold, he decides to go up and talk to her. They hit it off immediately and soon enough, they're dating.
The man is overjoyed that someone has accepted him despite his condition, and he decides to propose. The night before the big day, he tells his fiancee about his condition and warns her that he will fart all the time.
To his surprise, she just laughs and tells him it's not a big deal. The next day, they have a beautiful wedding ceremony and everything goes off without a hitch.
As they're leaving the reception, the man feels a massive fart coming on. He braces himself for the embarrassment, but to his shock, his new wife starts laughing uncontrollably.
"I can't believe you didn't warn me about this!" she exclaims between fits of laughter. "I have a condition too – I can't smell anything!"
