A man went to the doctor because he was feeling very unwell. The doctor examined him and said, "I'm afraid you have a rare condition where your body can't digest solid foods. You'll have to stick to a liquid diet from now on."
The man was devastated but decided to follow the doctor's orders. He started drinking all his meals in the form of shakes and smoothies. However, he quickly grew tired of the lack of variety in his diet.
One day, he decided to try something different and ordered a milkshake with whipped cream on top. As he was sipping on it, he suddenly felt a sharp pain in his stomach. He doubled over in agony and called the doctor in a panic.
The doctor examined him and said, "I told you to stick to a liquid diet! What did you eat?"
The man sheepishly replied, "Just a milkshake with whipped cream on top."
The doctor shook his head in disbelief and said, "I'm sorry to break it to you, but whipped cream is a solid food."
The man groaned in frustration and said, "Well, at least I can still have jelly, right?"
The doctor paused for a moment and then replied, "Actually, jelly counts as a solid food too."
The man burst into laughter and said, "So you're telling me I can only have liquid foods, but I can't even have whipped cream or jelly? That's just jelly stupid!"
The doctor couldn't help but chuckle at the man's pun and said, "Looks like you've still got your sense of humor, at least. Just stick to the liquid diet and you'll be fine."
And so, the man learned to stick to his liquid diet, but he never forgot the day he tried to cheat it with some whipped cream and ended up with a belly full of regret.
