Transcript for Snoring Man Stabbed With a Pen on Plane by Irate Passenger
Jim Avila, thank you so much. Now to a bizarre case of air rage. A southwest jet forced to return to the gate after a passenger stabbed the man sitting next to her with a pen. She was apparently angry because he was snoring. T.j. Holmes is here with that story. Reporter: We have all been there, right? If you have flown, you have flown with a passenger who was snoring loudly. What do you do? Do you leave it alone? Ignore it? Put headphones on? Do you wake them up? Do you assault them repeatedly with an ink pen. One passenger decided to go with the last option. We have seen our fair share of on board drupgss. There's a bomb on the plane! Reporter: But the incident that delayed this flight out of Chicago, you could say it rewrote the book on tarmac tension. Yeah, you don't stab me with a pen. Reporter: That's right. A pen. The video from on board flight 577 preparing to take off capturing the commotion after passenger Lenny mordarki's snoring caused passenger to get upset. Imagine being stung by bees. She went nuts. He screamed loud, almost like a little girl. Reporter: ABC news getting this image after the confrontation. It's some what disturbing. If you're a fan of drawing inside the lines. As flight attendants moved the weapon from the scene, the pilot returned the plane to the gate. The woman was escorted off. The flight did take off. Fellow passengers were none too happy. Sflit was such a minor incident. I think it inconvenienced a lot of people. Reporter: The female passenger was removed from the flight for poking her seat mate with a pen to stop him from snoring. As for Mordarski, he won't be pressing charges. In all seriousness, we have dealt with this. What do the etiquette experts say? You could try to nudge them. Quite frankly, it's part of the flying experience. You just need to deal with it. That's what headphones are for. When I snore, Ali just leaves. You can't do that. Captive audience. Thank you, T.J.
