Geek humor

From Flatuloon in comments at AmericaBlog:

An astrophysicist walks into a bar and says to the bartender, "Gimme a Mexican beer."

Instead of offering the beer, the bartender starts shouting "Okay, everybody out! Right now! Out you go!" and herds everyone out into the street.

"Damn," the astrophysicist says sadly, "I should've seen that Corona mass ejection coming."
