Improv Everywhere is at it again this week with another agonizingly cute “flash mob”-style public stunt. This time, they’re targeting Starbucks laptop users and imitating them, as IO “agents” haul their old desktop computers from home into the coffee shop and use them as if they were laptops (one girl even goes as far as to prop the clunky monitor on her while using it).

Towards the end, they interview one particularly troubled patron who isn’t in on the joke: “They’re schlepping!” he says with a sense of bewilderment. “But what is the benefit, though — I don’t get it. The most that can happen, what is it — you save electricity? But that’s, like, minuscule.”
