Our latest mental_floss t-shirts have come from reader ideas, and we want to keep it that way! We’re in the process of collecting slogans, and we’re offering $125 and a t-shirt to anyone for any idea we use. Just e-mail your submissions to flossyjason@gmail.com … You’ve got ’til Monday! We’ll announce 5 new winners in an upcoming newsletter.

Of course, if you just want to buy a shirt, we can help you with that too.

From now until Monday, all t-shirts in the store are 10% off when you use the discount code “shirt”.
