Is this a joke? $10,000 pants? Come on!

Pants for that price, to me, is no crazier than a bag for that price. But what's the big deal about these particular pants? They look like plain, ordinary pants to me...in other words, something I'm sure I'll eventually spill mustard on.
 
Good god that price? What, are they made of cashmere from a goat blessed by the Dali Lama and sewn with the undyed hair of a thousand virgins by Nina Ricca herself?
 
If you look at all the other Nina Ricci stuff, it is expensive but it has some nice design features. The reason you see the error on both the NM and the BG website is because they are owned by the same company. I bet the sale price is just a program they input.
