Doc is so old.... his graduation gift from medical school was a stethoscope made of a couple of small sea shells connected to a hollowed out pterodactyl breastbone and a length of velociraptor intestine with half a nutshell on the end.   Trouble was, his early diagnoses were not very accurate because the ocean was all he could hear when he put the shell earpieces to his ears.

Uvah is so old.... he was there when Beelzebub got kicked out of heaven for wild partying and disobedience.

RPGFX is so old.... the RP in his initials stands for Roman Prestidigitator.  He performed magic tricks in the Coliseum during interlude.

Doc is so old the writing on the stones had already crumbled to dust while he was dictating them.

RPGFX is a newbie so old doesn't apply. He needs to hatch first and find starkers in Doc's cave so they can interpret  the writing on the note left by the Pteradactyl that dropped him in the desert.

I'm so old all the zero's after my age had to be dropped because they became meaningless.

starkers is so old.... his idea of pirated software..... were the long johns and ugg boots he pillaged in a viking raid... 

Hehe, sydneysiders is so old.... she was a passenger on Cleopatra's barge when it was over-run by river pirates.

In fact, sydneysiders is so old.... she witnessed the building of that barge for its original owner, Cheops, builder of the 1st great pyramid.

in fact.... Cheops got the idea for the design while on a family outing and watching Starkers make sand castles with his little tin bucket that had been squashed...ending up in a pyramid shape...

In fact, if sydneysiders hadn't stood on my sandcastle bucket in jealousy, because I had one and she didn't, pyramids would have turned out round with flat tops to attract more sun rays to assist in the pharaoh's passage into the afterlife.

Now you know why the mummies remained in their tombs instead of ascending to the afterlife.... pointy tops.

k10w3 is so old... she volunteered to be the model so syd got the right style and fit, etc... that's because the blow-up doll Uvah loaned her quit halfway through the first session after getting jabbed by a dressmaking pin.

starkers is so old... it was his blow-up doll entombed with King Tut holding his implant for the ride to the afterlife.

xx is so old... you can find his nic inscribed on the cave walls in Normandy.

Uvah is so old... he's forgotten more than he ever knew. 

Shocking thing, that.... losing your memory in the latter years..... then spending the rest of your life looking for it.

I'm so old... I'd forgotten that I loaned King Tut my blow-up doll.  Dammit, and I've forgotten his address so's I can go 'round and ask for it back.

Nah, XX is so old.... he created those caves in Normandy.  Yup, dropped a tooth (he was gonna put under his pillow for the tooth fairy) down a rabbit hole... so he took his flint axe to it and the rest is history.
