When Richie first gets his head in the fire, the flames become massive. Yet in the next shot, the flames have all died down and all that is left is smoke.
When Richie is talking about how Red Native Americans eat hedgehog, there are four chocolate hobnobs on the fire. But when Eddie takes them off the fire to entice the hedgehog out, there are five.
In the tent, Eddie says he's had half a bottle of scotch, even though he drank the whole bottle. However in the UK, a 35cl (350ml) bottle of wine or spirit is known as a 'Half Bottle', Therefore his statement is correct.
When they are in the tent and going to sleep, Richie regrets missing Emmerdale Farm (British soap opera) and states that he will be missing Matt sticking his hand up a cow.
The character Matt refers to Matt Skillbeck who left Emmerdale in 1989, 3 years prior to their trip.
