- “Duff Beer for me, Duff Beer for you
I'll have a Duff, you have one too”
- ―The line repeated endlessly by the animatronics
Bart is so bored with the ride and unnerved by the animatronics, with five continents left, that he resorts to daring Lisa to drink the "water" the boats are floating on for a laugh. Although Lisa initially refuses, she obeys Selma's instruction to drink it after Bart's reaction to her refusal, calling her "chicken" and clucking, nearly causes an argument. However, one sip is enough to immediately cause Lisa to suffer severe hallucinations (it is implied that the "water" is some kind of alcohol). Due to Lisa rushing out of the ride in a deranged state, she, Bart, and Selma never finish the ride.
- The Little Land of Duff is a parody of "it's a small world", an attraction located at several Disney parks.
