Geological Time Scale

How do you remember what the geological column is? Do you remember what each of the periods are called? Do you know about Camels? Here is the way I remember the international stratigraphic column:

Camels often sit down carefully, perhaps their joints creak.

Camels - Cambrian
Often - Ordovician
Sit - Silurian
Down - Devonian
Carefully - Carboniferous
Perhaps - Permian
Their - Triassic
Joints - Jurassic
Creak - Cretaceous

Or alternatively you can refer to the following chart issued by the International Stratigraphic Commission:
