SWA flight attendant's funny safety brief

Airlines have been known to add a little comedy to liven up the otherwise boring but important messages about in-flight safety.

Think Delta Air Lines' totally tubular 1980's flashback or Betty White's starring role in Air New Zealand's safety video.

Other airlines embrace live stand-up comedy, as this hilarious video of a Southwest Airlines flight attendant Martha "Marty" Cobb published April 12 on YouTube shows.

"Position your seat belt tight and low across your hips, like my grandmother wears her support bra," she says.

Southwest Airlines has long been known for its wise-cracking flight attendants. "We're a fun-loving airline," says Southwest spokesman Dan Landson. "We like to put fun in your travel.

"As you can tell in the video, she definitely likes her job."

Not to mention there's nothing like a little comic relief to ease the stress of air travel.
