Granted, the genie takes you quite literally and you begin to grow a tumor on your brain which will continue to grow at an exponential rate, slowly morphing into a sentient being which takes a likeness to your own form. Congrats, you've just gained an identical Siamese twin, who happens to speak to you telepathically about only Gorgonzola and the Disco Demolition Night of 1979, consistently. It gets rather annoying.

I wish I didn't feel so alone.
