A flight attendant for Southwest managed to stuff herself into the overhead bin in an effort to surprise passengers as they boarded in Nashville on Monday.

Veronica Lloyd captured the incident on her Twitter, noting, “I think she was doing it to try and be funny and make the passengers laugh.”

The company followed up on Wednesday, saying, “Southwest employees are known for demonstrating their sense of humor and unique personalities,” adding, “In this instance, one of our flight attendants attempted to have a brief moment of fun with customers during boarding.”
