If you've been sitting on a great t-shirt slogan, now's your chance to turn it into cash. We've re-opened the mental_floss t-shirt submission mailbox, so you can send your best ideas to firstname.lastname@example.org. To see the kind of thing we go for, check out the t-shirt section of our store. We'll be checking that account periodically for the next couple weeks, and you'll be notified if your idea has been selected.
If we use your suggestion, we'll pay you $125 and, once it's available, send you your shirt. Plus, of course, eternal "I designed a mental_floss t-shirt!" bragging rights. (And it's a fun little nugget that'll show up when someone is stalking you via Google.)
