Mike saw his friend Paddy sitting alone at the bar, looking miserable.

“Hey buddy,” Mike said, taking the seat beside him. “What’s wrong with you?”

Paddy sighed deeply. “I just had a massive fight with the wife.”

Mike frowned. “Again? What happened this time?”

Paddy shook his head. “That woman fights for absolutely no reason at all.”

“No reason?” Mike asked. “Come on, Paddy. There must have been something.”

Paddy leaned closer and lowered his voice.

“Well, we were having a lovely evening. Dinner was good, the mood was right, and for once, everything was going perfectly.”

Mike nodded. “Alright…”

Paddy continued, “We went upstairs, and things were getting romantic. She was smiling, I was smiling, nobody was arguing, nobody was complaining. It was a miracle.”

“So what went wrong?” Mike asked.

Paddy sighed again.

“She started getting undressed. First she took off her jeans, then her top…”

Mike waited.

“And then,” Paddy said, “I just asked one simple question.”

“What question?”

Paddy looked genuinely confused and said,

“I asked her, ‘Why are you wearing your sister’s bra?’”
