A joke turned out to be more than British man Daniel Medforth, aged 36, bargained for after he took 35 Viagra pills in an hour as a joke. He then had to learn a hard lesson, reports the Sun after the man spent 36 hours in hospital.

“I ended up feeling sick, dizzy and hallucinating – everything I saw was green. And I had a massive erection that would not go away,” he said. “The paramedics were very professional but you could see they were trying not to laugh.”

Medforth now knows better and is wiser thanks to hindsight. He thinks he was very lucky to survive without deadly side effects.
