I was going to go with a priest, a rabbi, and a minister swim into a bar, but this is no joke.

This is the Clear Lounge Cozumel, where, for $38, you can enjoy everything that an underwater bar has to offer...except maybe the drinking. Who needs drinking when you can imbibe in scented oxygen?

From their website:

Clear Lounge® is the world's 1st underwater oxygen bar! Clear Lounge at Carnival Cruise's port of call — Puerta Maya — in Cozumel Mexico is now open! Using technology that is patent pending, guests can enter our underwater lounge and breathe enriched, scented oxygen while shooting bubble guns, playing Jenga, writing messages to each other and guests on the outside, and having their photo taken in our underwater photo booth– complete with a unique digital wall background and entertaining props. The fun lasts approximately 30 minutes including a short briefing. No diving experience necessary! If you can walk and breathe – you can participate in Clear Lounge*!


So, basically you'll come for the Jenga, you'll stay for the scented oxygen! Take a look:
