They took gullible out of the Dictionary ...

[Scumbelina]

The thread about the Scottish Unicorns reminded me that about 2 years ago Blue Peter - that I just happened to start watching when flicking through channels - had an April fools joke about a horse that was crossed with Rhino DNA to make a Unicorn ... & I believed it

What is the silliest thing you've ever believed?

[Athiri]

Once my friend and I were eating a stew round my house and I managed to convince her the carrots in it were actually 'Kacowcow beans.' We were about 8 mind. A few years ago my mum also sent me a postcard from Texas with a jackalope (rabbit with antlers) on the front, which I genuinely believed was a real thing for quite a while. Despite this when I was younger I didn't believe in mongooses. Like, I just thought the idea of a weasel-like creature that kills snakes was ridiculous and it was obviously a myth.

When I was really young I asked my mum where I came from. She said she found me in the rubbish outside amongst the cabbages. I believed her. My sister was told the that the stork brought her. I feel I got a raw deal!

[Sentient Treacle]

Not something silly I believed but one of my best friends thought that reindeer were mythical creatures.

Oh and this was until she was about 16.

Waiting for my Hogwarts letter turned out to be a bust...
