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.

This is an extremely easy to listen to podcast. You learn something new every time and get a few laughs in as well. Quick and to the point, CoK always provides some cool and random knowledge that you can break out on your friends or an unsuspecting date.
