Sorry, the very DAY that I will actually UNDERSTAND the mumbles of the safety briefing I will take care to attentively listen.
'Ladsandgtmen plesmywehaveyoutshenfortheflingpressionofdesaftyfushersofthi serplane' and so on and so on...
As for the rest there is the safety information card which typically is instructive enough to brief myself.
The only time I ever had an what I refer to as adequate saftey briefing that was audible, clear and understandable was on board of an aircraft that has the airlines name painted in bright orange on the fuselage, and yes, I paid attention.
