The 'clean underwear' is a new one! HAHAHA! I like how a lot of the FAs from many airlines are dressing up the safety briefing. People will listen and have a good chuckle!
This is a method to defuse people of air rage and it works. Breaking stress of tsa gate rape and airport traffic is important. We need more funny flight attendants
I flew WestJet back in 2004 and the purser during safety demonstration introduced the 3 other FAs as his ex-wife, wife & mistress! Boarding call was done by sock color!
