We've all heard the one about a man, a woman, and a dog who walk into a bar (punchline: "RUFF NIGHT"). But what about a man, a woman and a service dog who walked out of a moving airplane by using an emergency slide at LaGuardia Airport this week.

The incident happened on Monday morning on a Delta flight bound for Atlanta, Georgia. The plane was taxiing out of the runway at around 10:55 a.m., when the man, woman and dog opened a cabin door and activated the slide to exit the vehicle, Delta spokesman Morgan Durrant told CNN.

The Times spoke to fellow passenger Brian Plummer, who said he saw the couple change seats several times before the incident. The man stood up at one point, "ignoring a flight attendant’s order to sit, saying that he had post-traumatic stress disorder." Then they deployed the slide and left, with their service dog in tow.

The plane returned to the gate and everyone had to get off. "Maintenance technicians have evaluated the aircraft and is scheduled to return to service this evening," Durrant added.

Both passengers, who have been identified as 31-year-old Antonio Murdock and 23-year-old Brianna Greco, have been arrested, according to the Port Authority. They have been charged with criminal trespass, reckless endangerment, disorderly conduct and obstructing governmental administration.

The dog has been taken to Brooklyn Animal Care & Control; Greco was reportedly given a receipt in order to retrieve the dog.

And now, let us conclude by revisiting the greatest airplane emergency slide exit of all time.
