They say laughter is the best medicine, but what if you don't feel like laughing? Or even smiling, for that matter? Turns out fake laughs are the real best medicine.

And while I don't plan on making an idiot of myself in public like these people any time soon, it occurred to me that I have an entire collection of fake-laugh photos with my friends.

Happy (fake laugh) Hump Day!
