Said as "I am Dave EXCLAMATION MARK yognau(gh)t!"
The call of greeting between multiple yognau(gh)ts whenever they meet.
First used in YoGPoD 32: I am Michael McDonald and I Listen to the YoGPoD All Day. It was a saying taken from a fan-letter by "Nick Fuckface" from Australia describing his encounters with a shaken soda can which created a singularity. Simon/Honeydew approved of this saying and encouraged Yognau(gh)ts to use as a greeting. It stuck with the fanbase.
Yognaught: "...and I have the balls!"
Yognaut: "Eiffel tower."
