The 20 Minute YTP Challenge: Round 37 - Bertha and Charlie Chalk

ORIGINAL DESCRIPTION FOR ROUND 37:
A challenge where a group of YouTube Poopers have just 20 minutes to make a YTP of a source. This week, our two sources are the Bertha episode 'The Best Machine Competition' and the (fucking boring) Charlie Chalk episode 'Bert's Boring Day'. This is in place of what would have been a Postman Pat round, another Ivor Wood show.
