It was an old episode of Mysterious Universe that I found on my phone - I think from a few months back (don't know which number as it was playing in the car). You can find them here:

It's a top quality show and quite funny as well.
Thanks, I'll download some episodes and try it out.
Definitely worth it. They have a paid version too that gives you an extra episode and removes the ads which is well worth it.
