I could write it myself, but I recall the telling here (maybe on a different section) was pretty good.  It was about why we like to write reviews.  CAn anyone post it?  I'll try to recreate it, but I'm not sure I'll do it justice.

I guy finds himself on a deserted island with Heidi Klum.  They have enough food and water, but no way off the island.  After a few days of talking and geting friendly, and each of them getting horny, they start making love every day.  A month goes by and the guy says to Heidi, "Do you mind putting on my baseball hat?"  She puts it on. "Do you mind putting on this sweatshirt?" She agrees and puts it on.  "Do you mind if I call you Bob, just for today?"  Sure, she says.  "Bob," he says excitedly, "You won't believe who I'm fucking!!!"
