"The tightest spot in terms of being arrested?
"Just being daft, doing stupid stuff like trying to stick a spray can on the end of a massive long stick, so you can spray two storey high bunny rabbits.
"Getting stopped by police standing in an alleyway with this crazy stick and looking a bit stupid, so you have to think how are you're going to talk your way out of it.
"How did I do it? I'd pretend it was the first time I'd ever done anything like that. And when they'd seen what I'd done, they'd agree. That's why it's handy to be inept with a spray can, they fell sorry for you and let you go."
I'm speaking with  Charles Edwards, aka street artist Pure Evil, who is far from inept with a spray can.
Rather, the 45 -year-old, born in Wales, but now based in Shoreditch, has a  huge following, counting celebrities and fellow artists including Banksy among  fans of his pop art-esque work.
Influenced by the abstract expressionist art of his painter father John Uzell Edwards, Charles' first foray into art was through fashion. `
"I was the only new romantic in the village, so I got into fighting a lot", he laughs.  
"I headed to Kingston to study fashion, graduated, then went over to California which was a buzzing place to be at the time.
"I really enjoyed skateboarding, so street culture, and skater culture, the fashion, the work of Twist and Reminisce, it all got me into street art.
"By the time I'd been in California ten years I wanted to come back, street art, what was going on here, it was calling me."
If you've walked the streets of Shoreditch, chances are, that at some point or another, you'll have come face to face with a piece of Pure Evil art.
And more often than not, it's a bunny rabbit with twisted fangs.
"It all started with a bunny rabbit," he says. "I shot one when I was a kid, felt really guilty about it and one day, many years later, he reappeared in my sketch book.
"I felt he was coming back to wreak his terrible vengeance on me. I thought, he looked a bit evil, cute, but evil. So Pure Evil was born.
"I used to annoy people drawing these bunnies or writing welcome to hell opposite roundabouts, shops, you name it.  Some grandmas didn't like it, but a few people said it cheered them up on the way to work.
"It was never a guerrilla marketing campaign, rather, the voices were telling me to go out and paint bunny rabbits everywhere.
"It's therapeutic, I think a lot of artists, if they weren't artists they'd be serial killers."
The voices in  his head appear to have served him well. He's done shows all over the world and a guest appearance on BBC television show The Apprentice brought him to the attention of the masses.
Now he's exhibiting a new piece of work for Bookmarks at the E17 art house,  inspired by a Bible and a baby cam, the latter of which marks a new event in his life - the birth of his nine-month old daughter, upon whom he dotes , the fittingly named Bunny.
You're mistaken though  if you think he's given up the street art for fatherhood.
"I just ask permission before I go and paint anything now," he says. "I got a call not that long ago, from a couple who said: look you've painted on our front door, can we sell it? So I went back and repainted something better. It ended up covered in perspex. I'm in the perspex club, now I know I've made it!
"I love street art, the adrenalin of it, there's nothing like it. It's your chance to make a social comment on the times you're living in, on what's affecting you in your surroundings. Street art is the new Pop Art.
"But if I could paint anything, I'd love to do the Houses of Parliament - maybe a colour fade, a rainbow, perhaps I'd transform it into a blancmange..."
So are we likely to see Bunny following in her father's footsteps?
"No way.." Pure Evil laughs. "I want her to be an accountant. I need a good accountant, I  don't need another artist in the family, but an accountant...we definitely need that."
