December 13th

Both males and females possess mammary glands. On this day the females attempt to milk their partners in order to commemorate the evolutionary destiny of our species.

Sonia: Paul! My nipples are worn and tired. For once my teets may rest in peace as it is December 13th and I will caress your manly mammary glands in my palm.

Paul: *facepalm*
