Two medical students were walking down the street when they noticed an elderly man moving stiffly, his legs wide apart with each slow step.

The first student nudged his friend and whispered, “That poor man must have Peltry Syndrome. People with that condition walk exactly like that.”

His friend shook his head. “No, I think it’s Zovitzki Syndrome. That slow, wide-legged gait is a textbook symptom.”

Unable to agree, they decided to ask the man himself.

“Excuse us, sir,” one student said politely. “We’re medical students, and we couldn’t help but notice your unusual walk. We were debating which syndrome might explain it. Would you mind telling us what you have?”

The old man smiled, amused. “I’ll tell you, but first, why don’t you share your diagnoses?”

The first student confidently declared, “I believe it’s Peltry Syndrome.”

The old man chuckled. “You thought—but you’re wrong.”

The second student stepped in. “Then it must be Zovitzki Syndrome.”

The old man let out a hearty laugh. “You thought—but you’re wrong, too.”

Intrigued, the students asked, “Alright then, sir, what do you actually have?”

Grinning, the old man replied, “Well… I thought it was just gas. But I was wrong, too!”
