Doc is so old, he just realized that you don't appreciate a lot of stuff in school until you get older… little things, like being spanked every day by a middle aged woman—stuff you pay good money for in later life.
Gotta pay that one.
Some food for thought, there.
RedneckDude is so old that he enjoyed being spanked by a middle aged cavewoman while cuffed in manacles made from the pelvic bones of a velociraptor and covered in oil-of-ovineasaurus.
Syd is so old she was that cavewoman, who, while she didn't mind getting her hands dirty, introduced the paddle to spanking to heighten her bare buttocked customers pleasure levels.
Doc is so old he prompted the world's oldest profession when he paid a cavewoman for some exotic/erotic pleasures between the bearskins. Sadly, for him, he missed out when she decided to take the money and run. Hmmm, me thinks there's a song in there somewhere.
Uvah are so old he got caught matriculating in the back of class during a cave renovation lesson... "but it's not my fault, miss, the girl next to me got it out and started playing with it."
