(I started keeping this list at episode 512 so it probably neglects some things that happened earlier)

• 10something - "Which moon are we talking about?"
• 502 - "A very nice horse"
• 503 - "What happens if you eat only rabbit?"
• 512 - the furry animal scurrying across the winter landscape and startling Alan, and the subsequent bit where everyone decided to wait for it
• 609 - Rob Brydon and Ben Miller
• 701 - Alan sawing the table through
• 706 - Da Vinci painting, Rodney Bewes, etc
• 710 - Eating giant tortoises
• 716 - "Because it is."
• 814 - Graham Norton beheading Daniel Radcliffe (but basically the whole episode is hilarious)
• 815 - cupping your hands around your ears to hear better
• 1107
