Adam and Simon in “20x06”

Mushrooms, jesus, yeah, I did some mushrooms, can I just tell you? 'Cause, uh, no one told me what kind of dose you're supposed to take. You know, because I fell into the bad crowd at university. Don't go to university, kids. It's a disaster. And uh, they said, like, "Let's do some mushies!". I said, "I don't want to do too many, because drugs frighten me. I don't want to get off my head completely, I just want to get a bit giggly". They said "All right, just want to get a bit giggly...take a hundred". So I had a hundred fucking mushrooms...and so, went to Mars, you know. And that was the night that my scrotum shriveled up to the size of a pea. I had to spend the rest of the week just, like, looking at photographs of myself, my friends and family to try and remember who I fucking was. Nightmare. Don't ever, ever do it!

Good message there from the BBC.
