YMMV / Improv Everywhere

• Crosses the Line Twice: Going to a city that was 90.94% white and setting up a booth where people could Meet A Black Man.
  • Suicide Jumper... threatening to jump off a four-foot ledge.
• Retroactive Recognition: Many of the early agents were Upright Citizens Brigade players, and later became famous in their own right.
  • Aubrey Plaza was an agent in a few pranks, including Mobile Desktop.
  • Eventual Parks and Recreation and Ghostbusters (2016) writer Katie Dippold was a frequent agent in several early missions.
  • John Gemberling of Broad City and Fat Guy Stuck in Internet took part in several early missions, most prominently when he did a striptease during the Amazing Hypnotist Redux mission.
• Suspiciously Similar Song: Who You Gonna Call? features one of the Ghostbusters theme.
  • Similarly, Invisible Dogs uses a suspiciously similar (and more grammatically correct) version of "Who Let The Dogs Out" by The Baha Men.
• The Woobie: Done intentionally, of course:
  • First, with the two Rob missions. Poor lost Rob.
  • Also with the Worst Ice Skater Ever, at first. Then he subverts it.
