Lighter and Softer: The third Halloween podcast had one scary story, but the rest were just ridiculous... and a large portion of it focused on Lewis having his wisdom teeth removed, which was more painful-sounding than scary.

Scandalgate: The second YoGPoD, Sipsgate, in which Lewis randomly calls his internet friend Sips (who said to never, ever call him in real life except in emergencies related to their website, which at that time he was keeping up) three times for no reason other than entertainment. Luckily, the potential scandal and defriending is averted, and Sips is cool with it... as long as they don't call him again.
Sips later gets revenge for Sipsgate, by repeatedly interrupting the 2011 Christmas livestreams to ask about his mic volume.
Serial Escalation: The absolutely ridiculous lengths that Simon supposedly went to to protect his jam from Brian Blessed.
