An Archaeologist walked into a bar...

An Archaeologist walked into a bar. He showed his barkeep friend an ancient coin he'd found in an underwater ruin. It had old language written on both faces. He'd already deciphered the linguistics, and translated it for his curious barkeep buddy.

One coin-face displayed:
"To be indebted is to be helpless."

The coin's other face declared:
"To be helpless is to be indebted."

Before the evening waned, the Archaeologist was drunk and doubly confused. Meanwhile, his barkeep friend was so doubly confused he drank.
