Here's a tip: Be careful when operating heavy machinery.

Reality star Jesse James accidentally sliced off the tip of his right pinky finger on May 21 and posted a graphic photo of it to Twitter.

"Doesn't look like this little dude's gonna make it," the Monster Garage star captioned the photo. "Nice know'n you, little buddy." What a cute way of handling a medical emergency.

Jesse tells TMZ that he was working on a machine at his motorcycle shop in Texas when things got out of hand (so to speak).

Jesse is having surgery today on the finger and is reportedly not to stressed out about the incident.

This gives a whole new meaning to "giving someone the finger."
