Watch: Miming flight attendant entertain passengers
Southwest Airlines flight attendants are known for their occasionally irreverent pre-flight safety announcement creativity. Basically, the aim is to turn a boring, mundane and mandatory procedure into something more interesting and funny that passengers might pay attention to. Beyond that, if you're a nervous flyer the funny announcements are often a great tension breaker.
But in all my flights on Southwest I don't think I've ever seen anything like this flight attendant from Canadian low cost carrier Westjet who does his best Marcelle Marceu impression.
