Mark Zuckerberg has "secret escape passageway" under conference room

At least he knows how it's all going to end: fleeing pursuers who have located the secret tunnel in his corporate lair.

Zuckerberg doesn't typically work in a cordoned-off office like a traditional corporate executive. Instead, his regular desk is on the floor of Facebook's open-plan office, just like everyone — but executive-protection officers sit near his desk while he works, in case of security threats. Facebook's offices are built above an employee parking lot, but it's impossible to park directly beneath Zuckerberg's desk because of concerns about the risk of car bombs. ... There's also a persistent rumor among Facebook employees that he has a secret "panic chute" his team can evacuate him down to get him out of the office in a hurry. The truth of this matter remains murky: One source said they had been briefed about the existence of a top-secret exit route through the floor of the conference room into the parking garage, but others said they had no knowledge of it. Facebook declined to comment on this.
