A Dream of an Eggplant (a Japanese Traditional Joke)

Rakugo is a Japanese traditional performance which is played by a story-teller. Rakugo stories include funny stories, stories with warm human relationships, horrors and so on, and laughter is an important factor in Rakugo.

A Rakugo story is usually proceeded by dialogue which is played by a story-teller alone.

I found this joke (called "kobanashi" in Japanese) in a Rakugo story and became fond of it:

A: I heard you had a very large-scale dream last night.
B: Yeah, I did.
A: What dream? My friend, Tatsu, had a dream in which he sat on Mt. Fuji. That's really a big dream.
B: My dream is bigger than it. I dreamed an eggplant.
A: An eggplant? It doesn't seem big. ...How big was it? One foot?
B: No, bigger than it.
A: Two feet? Three feet?
B: No, bigger than it.
A: Was the eggplant as big as a tatami?
B: Bigger than it.
A: As big as this room?
B: More.
A: As big as this street?
B: More.
A: Well, what eggplant was it?
B: It was just like darkness with a calyx.

A: 昨晩、ずいぶんと大きな夢を見たんだってな。
B: おう、見たよ。
A: どんな夢だ？　辰っつあんは富士の山に腰掛けた夢を見たっていうけどな。そりゃ、でっけえ夢だな。
B: おれの夢のほうが大きいぜ。ナスの夢を見たんだ。
A: ナス？　大きそうじゃないけどな。・・・どのくらい大きかったんだ？　一尺か？
B: いや、もっと大きい。
A: 二尺か？　三尺か？
B: いや、もっと大きい。
A: 畳くらいの大きさのナスか？
B: もっと大きい。
A: この部屋くらい大きいのか？
B: もっとだ。
A: 町内くらいの大きさか？
B: もっとだ。
A: ふぅ～ん、どんなナスだ？
B: 暗闇にヘタがついたみたいだった。
