I've had something similar happen to me. Except they used bright pink nail varnish and painted my lips with this horrible tasting stuff you put on your nails to stop biting them. They even tied my shoe laces together. All of this was recorded on VHS as they did it. They considered cutting my hair (had long hair at the time) but thankfully they thought that would be going a little too far. In the morning my lips felt like they were on fire and the taste was awful- it tooks days to get rid of it.
Those b*&^%s!:D
