Across the Andes by Frog (18 Oct. 1977)

Palin and Jones parody madcap colonial explorers. The ones that go to foreign lands with a stupid ideas, ill prepared, knowing nothing about the local language and customs.

Captain Walter Snetterton heads off to the Andes to see if frogs can survive at high altitudes. The Peruvian natives are more interested in football and Wimbledon tennis. The head of the British Embassy is ill prepared to help them as he did not know that Snetterton and his crew were arriving until recently. They have trouble finding a guide at short notice. When as guide is found, she is an old woman who does not speak English.

The Sergeant Major is more interested in shooting the natives until he finds out the delights that the local women have to offer. Snetterton finds out that no one is minding the frogs who escape, then again the locals believe that his frogs have bought bad luck as there is an active volcano about.

Although a parody, you kind of guess that such things actually did happen in the latter part of the 19th century and earlier parts of the 20th century. It was nice to know Peruvian villagers were mad about the English FA cup final.
