Not sure it was a series as such. A set of four minute episodes that were included within
'Charlie Brooker’s Weekly Wipe', I think.

Anyway I've compiled them into two 30 minute collections.

Pt 01 (Eps 1-8);
00:00 - Time
04:21 - Crime
07:54 - Evolution
11:13 - Computers
15:19 - Money
19:02 - Churchill & WWII
23:00 - Philosophy
26:31 - Climate Change

Part 02 (Eps 9-15) is here;
