Harry Potter actor Jason Isaacs has revealed he was left in agony after a bedroom mishap involving ointment.
Lucius Malfoy star Jason, 58, said accidentally rubbing the cream into his nether-regions was the worst pain he's ever been in.
The British actor says he was in bed at night and had Vicks on his hand and was left in agony following the incident as a kid.
He told the Kermode On Film podcast: "The first time I remember hurting myself at all was when my best friend gave me some Vicks VapoRub when I had a bad chest when I was 12.
"I rubbed it on my chest when I was lying in my bed at night, where I sleep naked.
"And then I stroked myself... and I leapt out of bed screaming, probably for my mother.
"I needed to wash the nether regions for quite a while before the stinging went away."
He added: "That's the first pain I remember. There have been many things since then, but that stays with me.''
Isaacs was discussing his latest TV series Good Sam, which he is currently filming in Toronto, Canada.
VapoRub is designed for the use on the chest, back and throat for cough suppression or on muscles and joints for minor aches and pains
