A "Murky Sauna" is a drop shot. First warm 4 oz. of Guinness in either a pan or microwave. It shouldn't be boiled, just warmed. Then drop an half ounce of Bailey, and an ounce of vodka. For added murk use Pernod instead of Baileys.

Rupert "That sounds awesome......wait a murky what?"
Chad "You don't know what a murky sauna is.......really?!?
