Watch Kate Winslet Make Butt Faces and Talk Square-Shaped Poops!

Of course, Fallon comforts her and promises she looks fine before (ironically) forcing her to make the weirdest face she could using the stretch filter.  Winslet proceeds with the challenge, laughing all along and telling the crowd, "Look, it's good to be willing!"

The photo ends up being hilarious, but not as funny as her comments while Fallon attempts the same face.

"It does look a little bit like you're trying to push out a square-shaped poop, I have to say," she tells the late night host after he reveals his ugly selfie… LOL!

The next round they decide to use the mirror filter, which results in some pretty awesome photos. While Fallon manages to create a photo that looks relatively similar to his actual face, Winslet's is anything but!

"Oh no, this is awful!" the Steve Jobs actress exclaims. "I have no nose!"
