"How do I get out of here?"

Mani laughed. It was a rumbling noise that sounded more like an earthquake.

"I would have thought it would have been obvious", he said.

"I tried to get out the front door, but it was locked!" Jake protested.

"And if you can't get out the front door?" Mani asked, smiling. "What then?"

Jake racked his brains. He felt like the answer was at the same time obvious, and also a puzzle.

"The back door?" he suggested.

"Correct", Mani said. He slapped Jake on the back, nearly knocking him out of his chair. "I knew you'd get it!"

"Thanks!" Jake said, once he'd recovered his bearings. "That's really useful information!"

"No problem", Mani replied.
