Chocolate-Orange Cream Pie (a.k.a. if you want something in particular you should go get it yourself)

My younger son had fallen asleep in the car earlier this week, so I sent my older son into the market with $20 and instructions to "buy a pie crust, preferably organic"... He came out 10 minutes later proudly producing an Oreo-branded chocolate cookie crust, "that was only $2!" He "couldn't tell if it was organic because there was so much writing on the package, but it will DEFINITELY be yummy!!"W
