Kevin Hart Confronted Ice Cube On Why He Never Laughs

When your idea of a "Good Day" is just not getting murdered, it's understandable that you don't smile a lot, but Ice Cube takes it to a whole new level.

The actor/rapper/mogul is known for always having a straight face, and now we might know the reason why. While on "Conan," Kevin Hart revealed that he once confronted Cube on why he never laughed. And though he got an answer, he's still a little confused by it.

"Conan" airs weeknights at 11:00 p.m. ET on TBS.
