A Cambridge graduate and an Oxford graduate

After they’ve been talking for a while, the Cambridge graduate says to the Oxford graduate,

“You know, I can tell you’re an Oxford graduate by your charm, your intellect, your

sophistication, and your worldly wisdom.”

The Oxford graduate smiles and responds,

“Thank you. You know, I can similarly tell that you’re a Cambridge graduate.”

The Cambridge graduate also smiles.

“How nice. What was it that gave me away?”

The Oxford graduate takes a sip of his martini and explains,

“Well, I saw your college cuff-links when you reached up to pick your nose.”
