North Korea: Border Patrol
On the occasion of North Korea's decision to bar foreigners from participating in this year's marathon in Pyongyang in order to avoid the spread of Ebola, here are some other memorable reasons that have been used by the hermetic kingdom in order to restrict foreign participation in local athletic and cultural events:
Spread of MERS
Spread of plague/black death
Dissemination of Taylor Swift's bootlegs
Circulation of malware-loaded flash drives
Zombie attacks
Infiltration of capitalist memes
Dissemination of Lance Armstrong's wristbands
Circulation of Sony's "The Interview"
Interracial mating, flirting & bantering
The Macarena
