In the nineties, Saturday Night Live ran a series of skits centered around an unfrozen caveman lawyer, played by Phil Hartman. This was a typical episode:
One hundred thousand years ago, a caveman was out hunting on the frozen wastes when he slipped and fell into a crevasse. In 1988, he was discovered by some scientists and thawed out.
He then went to law school and became … Unfrozen Caveman Lawyer.
