An atom walks into a empty bar...

[Gleb Gamow]

Atom: Bartender, is it always this crowded?

[Gleb Gamow]

A Nu instantly appears in front of a bartender tending a bar.

Bartender: May I help you?
Nu: Yes. Have you seen my counterpart? <then disappears>
Bartender: <to Mu setting at the bar> And you asked why this joint's named Atom.

[Gleb Gamow]

Two atoms walk into a bar.

Atom 1: Come on, let's get wasted. Tomorrow, we're goin' experience that ride over at CERN.
Atom 2: Sure the hell hope it'll be fun than our trip last year to Fermi starin' up at buffalo asses as we traveled near the speed of light.
