During the Mail Order Bride skit, part of the safari decor (antelope horns) falls off the wall, the first time Carol comes back from fetching wood. When she gets up from sitting at Peter Lawford's feet, the antelope horns are back up on the wall. This indicates that they spliced segments from both of their show tapings. (Carol had previously also banged her head on a lamp.)
The intro wording says the location is the Amazon, but the set decor is decidedly African safari, and so are the clothes the men are wearing---complete with 1908 pith helmet. (Examples: there are no zebras nor antelopes in South America, yet there is a zebra skin rug on the settee and on the floor, and the skull of some sort of antelope with huge horns on the wall.)
