 FACT: A clip from _Mothers Day (1980)_ (qv) of Tiana Pierce (qv)  with blonde braided pigtails stabbing someone with an electric  carving knife is mistakenly credited to the horror documentary  _Dont Scream Its Only a Movie (1989)_ (qv), perhaps partly because  _Mothers Day (1980)_ (qv) was featured in  _Dont Scream Its Only a Movie (1989)_ (qv).
