My dad told me a story a while ago about this.
When he was growing up in Texas there was a fanatical woman at his church that would always go the whole mile and then some. Flailing hands in Church, bowing down repeatedly, you get the idea. One day, during the sermon, she starts speaking in "tongues", and the pastor paused the sermon and asked for somebody to come forward and translate, since if someone is speaking in tongues, then there shall be someone there to translate. However, nobody came forward to translate because she wasn't speaking in a foreign language, she was just babbling nonsense. After a couple of minutes, an usher came and led her out into the lobby.
