Teena Marie- Must Be Magic (1981)

I took notes health class. I work in the medical profession. I am a woman of common sense.
I'll tell you, though: when somebody does that "detachable thumb" trick, I never like to discount the fact that the person might be magic and/or involved in some sorts of suburban witchcraft offshoot. Up until now, I have been 100% incorrect, but it still feels like a worthy suspicion.
