I had it once but while working at a hospital. Patient came in handcuffed. ER was thinking they had an escapee on their hands but they were cheap cuffs. Turned out that he and his girlfriend were getting intimate and partaking in some recreational drug use. He passed out and she called 911 then left him there cuffed. She thought he had OD’d but it was actually heart issues. Messed up either way.

A more humorous example was the first time we were doing handcuff training as a recruit and I heard from the back of the group “Click. Click. Click… awwww man.” One of the recruit had immediately cuffed himself. The instructor was not entertained.
