You know how it is. You wait ages for a new Rich Fulcher project then two come along at once!

Hot on the heels of BBC Three’s new Sexy Murder miniseries, Fulchybaby returns to Comedy Central’s YouTube channel with a brand new run of his smash hit factual show Questionable Science.

In the first edition, which you can see below, Professor Rich wonders what would happen if cats became extinct, and a mysterious new student joins the class. Welcome back, Rich. We really have missed you.
