"But why is it made of diamond instead of glass?"

"We don't know. That's the Conundrum."

"But I'm still curious: why is it diamond, instead of glass?"

"We've no idea, no idea at all. That's the conundrum, you see."

"Hmm... looks like a big plus sign. What could that possibly mean?"

Perhaps my favorite Tintin album is Le Secret de La Licorne.

Trois frères unys. Trois Licornes de conserve vogant au Soleil de midi parleron.

Car c'est de la lumière que viendra la lumière. Et resplendirra

However, I actually prefer certain passages as they're rendered in the English translation (whose authors were good friends of Hergé).

Three Brothers joyned. Three Vnicornes in company sailing in the noonday Sunne will speak.

Of course, I also enjoyed Steven Spielberg's film adaptation (though not particularly the music, though some may accuse me of heresy for dissing John Williams). I particularly liked that the writers managed to work in Bianca Castafiore...

"Ciel! Mes bijoux!"

"...and X never, ever marks the spot. Seventy percent of all archaeology is done in the library. Research. Reading. We cannot afford to take mythology at face value."

--Indiana Jones and the Last Crusade

"Well, ah... now what's that supposed to be coming out of there?"

"Lightning... fire... the power of God, or something."

"I'm beginning to understand Hitler's interest in this thing."

"Oh, yes. The Bible speaks of the Ark levelling mountains and laying waste to entire regions. An army which carries the Ark before it is invincible."

--Raiders of the Lost Ark

"X marks the spot."
