Three noble gases walk into a bar.
Every other gas looks at them in awe.
They turn their noses up to them.
They have no time for frivolous regular gases.
"I will have a glass of cognac, barkeep," says Xenon.
The keeper of this dingy bar looks at Xenon oddly.
"Sir," he says, "This is a dingy bar. We don't serve cognac."
"I expected as much from lower-class gases."
