Friends: how many of us have them? Do you think you know your friends inside and out? Can you say the same for them, that they know you like a book? Could you put your knowledge of your best friend to the test?

We tried that with Lil Duval and Deray Davis as they promoted their new film, Grow House, here in New York City. The two actors play Darius and Pat respectively, two best friends who love to indulge in “herbal aromatics” but are also looking to learn how to grow them.

While aboard the aptly-named “Blunt Force One,” we found out just how well the two “bud buddies” knew each other both on and off-camera.
