I bribe someone who goes to /b/ with some....items (let's go with that). They bring the diamond back to me, and I proceed to wash the diamond in plenty of soap and water....and bleach. I then put it in the pouch of a boxing kangaroo.
I tie the kangaroo arms together while it's sleeping and take the diamond. I then feed the diamond loch ness monster.
I don't believe in the monster, so I just find the diamond at the bottom of the lake. I give the diamond to a giant squid, which takes it in its beaked mouth to the depths.....
I ride a sperm whale to the depths of the ocean (Screw water pressure! and air....), and the whale does an epic, epic battle with the squid, in which I grab the diamond and escape to the surface. I then take the diamond and put it in Lady Gaga's hair. Try to find it in THAT!
waits will Lady Gaga shaves her hair off, steals hair, sort it out and sells it to her fans, find diamonds Gives Diamond to Katie Price who does something very....dirty with it and it is never seen again find that!
I take it out. I then open my hand, outstretch my arm, and just stand there, with the diamond in my open palm.
I knock you out and steal your shoes. I donate your shoes to a charity and they go to an orphanage right away!
I steal the shoes from the orphanage, and get arrested and they send me to a place where I dig "Holes" :Trollestia: I bring the diamond with be to the desert, while I dig holes.
I obviously go to the last World and rescue Peach, then slap Bowser in the face. Then I place the diamond somewhere where it CAN'T be found. BWAHAHAHA
I get in the heart of gold and use the infinite improbability drive to find the diamond The diamond is sealed in a box with THE QUESTION!
Since that question isn't actually specified, I can give any answer I want and open the box! Ha! I hide the diamond somewhere really really really inconspicuous... you'll never guess where I put it!!!
I use my wall hacks and find the diamond using my diamond sensors. I put the diamond in my Everypony bank account.
I take paypal and haxxorz into your account. After all, it IS an Everypony account, and i can do it. I take the diamond, and hide it in my house, under a shelf, under a thin amount of air, under a tv.
I go to your house and find the diamond in your house. [Doesn't feel like searching.] I hide the diamond in my diamond room with diamonds everywhere.
I take them all, and sell them all. All besides one. And that one is the diamond we're looking for. I Take the diamond and hide it in my signature.
