Before you listen to this BBC podcast, I'd like to introduce myself.

My name's Stevie Middleton and I'm a BBC Commissioner for a Load of Sport Podcasts.

I'm lucky to do that at the BBC because I get to work with a leading journalist, experienced

pundits and the biggest sport stars.

Together we bring you untold stories and fascinating insights straight from the players'

mouths.

But the best thing about doing this at the BBC is our unique access to the sport in world.

What that means is that we can bring you podcasts that create a real connection to

dedicated sports fans across the UK.

So if you like this podcast, head over to BBC Sounds where you'll find plenty more.

We use these cases to explore what research can teach us about why people, including you

and I, do bad things.

I'm criminal psychologist Dr Julia Shaw.

And I'm Sophie Hagen, the stand-up comedian.

And it's April 1st, so we considered playing an April fool's prank on you, but then after

doing some reading, we decided against it.

Also, because people who do pranks are evil and horrible and I hate them and I would never

do that to you.

Because I know this is unresolved trauma, I know this is trauma reaction, I just don't lie

to me, I can't do it.

But also because we found a story for you about, let's say, an April fool's day prank

that went a bit wrong.
