Kathy: What's next on the map, Barney?
Barney: [reading the back of the map by mistake] Hm, okay, let's check here and uh... oh, no!
Kathy, Min, Michael, Derek: [ad lib] What is it, Barney?
Barney: The words and pictures are all gone! The map is all empty! I just don't understand what could have happened...
[mumbles]
Michael: Barney?
Barney: Yes, Michael?
Michael: You're holding the map backwards.
[pointing to the other side of the map]
Michael: The words are on the other side.
Barney: They are?
[Michael nods as Barney flips to the other side of the map]
Barney: Oh, they are!
[giggles]
Barney: Okay...
[clears throat]
Barney: Let's see now, uh...
[reading the words upside down]
Barney: tray eechem, wee ray un sapeh shum...
[mumbles]
Barney: ...oh, now the words are upside down!
Kathy, Min, Michael, Derek: Barney!
Barney: [giggles] Just kidding.
