Improv Everywhere just released their latest mission, High Five Escalator on their website today. Agent Lathan gave out 2,000 high fives by standing next to a subway escalator during the morning rush (umm ouch). Five additional agents were spread out along the adjacent stairs holding signs that prepared commuters for the slap happy fun. This event was not as magical as Frozen Grand Central or as eye popping as No Pants! Subway Rides but it still managed to earn smiles from thousands of cranky subway riders.
