"I can reach!" Much said with an enthusiastic squirm, twisting his other arm awkwardly around his body, slowly managing to snake his fingers into his pocket. To make enough room between their bodies he had to press his shoulder extra firmly into some part of Stutely behind him, but he tried to do it slow so it wouldn't hurt. "Almost almost almost..."
His fingers didn't hit his knife first, though.
His fingers hit on a very bad idea.
A very bad idea that was definitely going to get him yelled at.
Much closed his fingers, and wriggled his hand out of the net, extending his arm just far enough out that all three of them were in frame when he took the selfie.
Yelling was temporary, but this photo was going to make them all laugh for years.
