Over the years, you guys have come up with many of our best t-shirt ideas. Let this serve as a reminder that we're always in the market for a great idea. Send it over and if we decide to use it on a mental_floss shirt, we'll send you a check for $125.
I've set up a new email address for t-shirt slogan emails — firstname.lastname@example.org. (The previous account is like 94% spam.) You can check out all our slogans here for inspiration.
