It may be too late for Christmas 2011, but here's the perfect gift for the social network-a-holic you love in 2012: the Facebook shower curtain.
The curtain replicates a Facebook profile page (though not in the new Timeline format!).
It includes a cutout where a profile picture would go, near the shower head, so you can pose for a living avatar.
It doesn't appear you can customize the curtain, so you may be stuck with such "posts" as one from Bath Tub which says, "Why did the bank robber take a bath? So he could make a clean getaway..... hahaha."
