You don't want to mess with Conor McGregor. You don't even want to play fight with him. Things could get ugly real fast.
That's a lesson Conan O'Brien almost learned the hard way. When McGregor made an appearance on "Conan," he decided to practice one of his new kicks on the late night host.
The technique is a half-moon capoeira kick that McGregor wants to pull out and "ping across Nate Diaz's head" when the two meet at UFC 196 on Saturday. O'Brien can attest, this kick looked very effective from up close.

McGregor said he didn't want to hit Conan, but the kick still came perilously close to O'Brien's gorgeous red locks. If that kick had made contact, there would have been a job opening for a new late night host.
