On the E4 show Look Into My Eyes, a participant called TV hypnotist Archie Manners to find out how often her boyfriend checks out girls.
Scott the boyfriend was hypnotised to slap his forehead whenever he checks out a woman passerby. His forehead develops a huge red mark from all the self-induced slapping.
Archi Manners then kicks it up a notch and tells him to physically show when he has sexual thoughts. It’s hilarious.
