Who Wants to Sail Down the Amazon, Anyway

S2 E9: Maternal grandfather Harry Madison visits the Corbetts, and Eddie can hardly contain himself in anticipation of joining him on an archaeological expedition down the Amazon River. Tom Corbett flatly rejects the idea but comes to realize the trip is just Harry's dream. When Tom confronts Harry, the grandfather admits it's just an old man's wish, but saves Eddie from disappointment by giving his tent, bedroll and inflatable raft to his grandson.
