Torsonic Polarity Syndrome, or TPS for short, is a rare birth defect, which causes a person to grow a buttocks where his or her head should be. According to Stephen and Martha Thompson, more than 11 people worldwide suffer from this condition and although some may think that they would have faces where their buttocks would normally be, this is not the case. Underneath the buttocks, is a fully functional face with a full set of fully functioning organs.
