I won't tell you how old oberebo is, because Id' hate for someone to identity theft him, but:
Oberebo is so old, he remembers when the Great Wall of China was just a fence.
Oberebo is so old, he knew the Dead Sea before it got sick.
I'm not saying oberebo is old, but his ears are still ringing from the Big Bang
Oberebo can tell you which came first, dirt or sand.
