It's New T-Shirt Week!! To celebrate, we'll be unveiling one new mental_floss shirt each day, and offering a one-day-only 10% discount.

To order yours, head over to the mental_floss store, add it to your cart, and use the code "hobbit" during checkout. (For the women's shirt, use the code "whobbit.")

Today's shirt "“ also available in women's fitted "“ was a joint effort between reader Casey Harris and mental_floss co-founder Mangesh. We asked Casey to tell us a little about himself, and here's what he was willing to share:

"Casey is a corporate attorney who reads every issue of mental_floss cover-to-cover, if he can wrestle it away from his far-more-intelligent wife, Laura, when it arrives in the mailbox. They have two little boys ages 4 and 1, who keep them super busy and turning to mental_floss regularly for mental stimulation and the occasional sanity check!"

We'll also be linking back to three stories (somewhat) relevant to the shirt's slogan. This batch is kind of a stretch:

1. Meet Peter Jackson

2. Quiz: Best Pictures

3. Houses Made of Straw (including one that looks like a hobbit house)

See what else the mental_floss store has to offer this holiday season.
