- The Historical Dating Service sketch featuring the infant Mary Queen of Scots... as played by Mathew Baynton's own infant son, wearing a tiara and sitting in his father's lap.
- Weaving in audio from one of Winston Churchill 's speeches at the end of the RAF Pilots song is weirdly heartwarming considering the actual song.
- Also the fact that this song says "Some of the bravest men were Polish and Czech", giving a Shout-Out to some of the other nationalities that helped win the Battle of Britain.
- The love ballad of Queen Victoria and Prince Albert. After so many tales of royals marrying for power and money, it's nice to hear about a couple who really did care about each other.

Both times you can see that these guys really all care about each other, with Ben even referring to Jim once with the fond nickname "Goose".Ben: [with his hand supportively on Jim's shoulder] Talk to me, Goose.
"12 years ago today was my first day on set (a very cold quarry) with three strangers. Seem nice enough I thought. Weve done a lot of dressing strangely in cold places since then, and Ive loved every single one. Happy Idiotiversary, fellas x"
