[[File:Gag-overthemouth-lorelei-kibf903.jpg|thumb|The basic over-the-mouth gag]]
The '''detective gag''', or '''over-the-mouth gag''' (sometimes abbreviated to '''OTM'''), is often described in fiction (particularly crime serials) as preventing the subject from speaking through the use of soft materials such as [[scarf|scarves]] or [[bandanna]]s. The long scarf or bandanna is pulled over the subject's mouth and tied at the back of his/her head. In practice, it does not silence the subject very effectively. Images of OTM gags, usually applied on women, have been prevalent since the [[serial (film)|film serials]] of the early 1900s. For this reason, the OTM gag is associated with the typical [[damsel in distress]]. OTM gags are often combined with stuff gags to make them more effective in silencing the wearer.
