Two medical students were walking along the street when they saw an old man walking with his legs spread apart.©JOKEDEMO.COM

One of the students said to his friend: "I'm sure he has Petry Syndrome. Those people walk just like that."©JOKEDEMO.COM

The other student says: "No, I don't think so. The old man surely has Zovitzki Syndrome. He walks just as we learned in class."©JOKEDEMO.COM

Since they couldn't agree they decided to ask the old man. They approached the old man and one of the students said to him: "We're medical students and couldn't help but notice the way you walk, but we couldn't agree on the syndrome you might have. Could you tell us what it is?"©JOKEDEMO.COM

The old man said: "I'll tell you, but first you'll tell me what you think."©JOKEDEMO.COM

One of the students said: "I think it's Petry Syndrome."©JOKEDEMO.COM

The old man said: "You thought.......... but you're wrong."©JOKEDEMO.COM

Then the other student said: "I think you have Zovitzki Syndrome."©JOKEDEMO.COM

The old man said: "You thought.......... but you're wrong."©JOKEDEMO.COM

So they asked him: "Well, what do you have?"©JOKEDEMO.COM

And the old man said: "I thought I needed to fart. I thought.......... but I was wrong."
