This flight attendant had passengers in fits of giggles after he delivered a hilarious pre-flight safety announcement.

Footage shows the steward delivering a series of jokes during a Southwest flight from Chicago to Manchester on St Patrick’s Day.

In the video, the attendant begins his speech saying: ’’We’re going to ask you to pay attention to my ex-wife up here and her two new boyfriends there in the central aisle way,''

''In the event you haven't been in an automobile since 1960, flight attendants still have to show you how to fasten a seatbelt,'' he continues.

''The seatbelt needs to be low and tight across your hips just like the hot pink Speedo I am going to wear when we get to a hotel hot tub tonight at Manchester,'' he adds as passengers burst into laughter.

He then continues his tirade of jokes for another three good minutes.

The clip, filmed in March 2015, has recently gone viral.
