Cindy and Barbie, two blond sisters, had promised their Uncle, who had been a seafaring gentleman all his life, to bury him at sea when he died. Of course, in due time, he did pass away; and the two blonds kept their promise.
They set off from the shore with their uncle all stitched up in a burial bag and loaded onto their rowboat. After a while Cindy says, 'Do you think we're out far enough, Barbie?'
Barbie slipped over the side; and finding the water only knee deep said, 'Nope, not yet, Cindy.' So they rowed a little farther.... Again Cindy asked Barbie, 'do you think were out far enough now?'
Once again Barbie slipped over the side and almost immediately said, 'No, this will never do, the water is only up to my chest.' So on they rowed and rowed and rowed; and finally Barbie slipped over the side and disappeared.
Quite a bit of time goes by and poor Cindy was really getting worried, when suddenly Barbie broke the surface. Gasping for breath she said, 'OK, it's finally deep enough. Hand me the shovel.
