A woman aboard a Southwest Airlines flight Thursday afternoon couldn't stand the snoring of a man sitting nearby, so she stabbed him with a pen.

Passengers aboard the already delayed Flight 577 out of Midway Airport were perturbed when the pilot was forced to circle back to the gate where Chicago Police escorted the woman off the plane. Other passengers tweeted their experience, noting the woman was "just smirking" as the flight was stalled.

A Southwest Airlines spokeswoman said no arrest was made.
