An elderly couple was sitting outdoors at a cafe

An elderly couple was sitting at a cafe when they noticed an old man struggling to cross the street. The man said to his wife, “He surely has bad arthritis to walk like that.”

His wife replied, “No, that’s definitely old-time rheumatism.”

Unable to agree, the man approached the old man and asked, “Excuse me, sir, but my wife and I saw you having difficulty crossing the street. I told her that you have arthritis, but she insisted you have rheumatism. Which one of us was wrong?”

The old man replied, “The three of us were wrong.”

“Three of us? How so?” the man asked.

The old man explained, “You were wrong when you said I had arthritis, your wife was wrong when she said I had rheumatism, and I was wrong when I thought I just had to pass gas.”
