Here we learn a few valuable lessons:

1) Fred Flintstone is so desperate for pussy he will try to hook up with a woman who has the face of a caveman.

2) The tidal forces of Bedrock's ocean are so powerful, not only can you lose your own clothes, but if two people are struck by a wave, they will actually switch outfits.

3) Barney is a master of disguise or Fred Flintstone is an idiot. Either way, that's one ugly cave "chick."
