The doctor was an old lady already. After a few initial questions, she took her magnifying glass to examine him. Serious?! Yeah... She didn't hesitate. It was embarrassing for him indeed. After looking very closely at his private parts, she got to a conclusion: - "allergy"! Take this medicine every time you feel like scratching.
He came back home thinking... Never had any allergy, what would be the cause? His smartphone vibrated. He received a text message from the office asking about the power point presentations that were still to be finished. Immediately, he felt like scratching. He laughed*. So much work to do and he was literally scratching his private parts. It was clear for him now. He had power point allergy.
*In Brazil, when someone is neither working nor doing anything useful, they say the person is "scratching his private parts". It's an expression widely used in the country, in Portuguese of course.
