panties on a plane

There were three old black ladies getting ready to take a plane trip for
the first time. The first lady said, 'I don't know about you two, but I'm going
wear my bright hot pink panties before I get on the aeroplane.'
'What are you going wear them for?' the other two asked.
she replied, 'Because, if the plane goes down and I'm out there
lying butt-up in a conefield, they going to find me first.'
The second lady said, 'Well, I'm going wear my very flourescent
orange panties.'
'Why you going to wear them?' the others asked.
The second lady answered, 'Because if the aeroplane goes down
I could be floating butt-up in the ocean, they will easy see me first.'
The third old lady says, 'Well, I'm not going to wear any panties.'
What? No panties?' the others asked in disbelief.
The third lady says "Thats correct ladies, you heard me right no panties".
The reason i'm not wearing any panties, is this if this aeroplane
goes down Ladies, they always look for the black box first.'
