They were right... I never knew I wanted to know these things...
The first episode I listened to was 'Are there lazy ants?' then I was hooked and have been binge listening ever since. Great topic. Great format. Love the theme score music especially.

Very intelligent and funny podcast; you always learn something you didn't know

Love this podcast! It's so strange and interesting! I just wish they'd put out more episodes!

Quirky questions are investigated. Usually with some good laughs thrown in.
