[Dad joke] A man would experience severe pain in his eye every time he drank tea

He went to his doctor, who referred him to an eye specialist. They performed every test possible, but found nothing wrong with his eye. Since the pain was still persistent, he showed a number of specialists, had every test done on him, consulted quacks, and all to no result. He still felt excruciating pain whenever he had tea.

Finally, he decides to visit an old sage. The sage sits him down and pours him some tea. As soon as he takes a sip, he feels the pain again.

The sage sets his own cup on the table, and quietly says

"Next time you drink tea, remember to remove the spoon from the cup."

[This is my dad's favorite joke]
