One day, you might find yourself working alongside Father Mulcahy from M*A*S*H. He may agree to take a photo with you. And when he does, don't you want to be wearing a mental_floss t-shirt?

Our buy-2-get-1-free sale ends at midnight (EST), so head over to the mental_floss store, fill up your cart, and enter the code getonefree before checkout.

Once your shirts have arrived and you've been photographed with a famous TV actor, send that picture to flossypics@gmail.com. Maybe one day you'll see yourself here on mentalfloss.com, or on the Letters page in the magazine.

[Thanks to Mary Woll for sporting the "I'm No Rocket Surgeon" shirt and sharing her photo. She and William Christopher worked on the national tour of the musical 'Church Basement Ladies.']
