The Eighth Wonder of the World

Brother B: Hey, do you know what the 7 wonders of the world are?

Brother M: I think the pyramids in Egypt and the Great Wall of China, but I don't know the rest.

Brother B: I think also Taj Mahal. Oh, and Tiramisu!

Brother M: What? Tiramisu is a dessert.

Brother B: You know, that place in Peru.

Brother M: Oh, you mean Machu Picchu!

Brother B: I can't believe I just said that. I was thinking of the kind of cake I wanted to eat.
