Talk about a bad trip! Robbie Williams once took LSD and he figured it would be a good idea to stab himself while he was high on the drug.
"It was at Shelley's [nightclub] where I had my first acid experience. We were in Golden Hill, in someone's kitchen probably," he wrote on his blog.
"I was given a tiny piece of paper to ingest. E's were too expensive for the Potteries. £15 - who could afford that? There was a band called The Prodigy performing that night and I thought they were really good.
"Afterwards we drove up to the garage and the police were on the forecourt. S**t, I thought. I want to go home, I'm scared. There is only one place I want to be - at home with my mum.
"So I decided to go downstairs and stab myself. Mum came out of her room and said, 'What are you doing?' I'm just going downstairs to stab myself – do you want a cup of tea?" the singer then told his mother.
Luckily his mother talked him out of it and he lived to see another day. We're pretty sure that was the last time he experimented with the drug. It probably scared the daylights out of him!
