A video shoot in Nepal for an Internet comedy series took a serious turn on Saturday as the earth began rumbling.

The Nepali Pranksters were in the middle of shooting an episode for their hidden camera series when the magnitude-7.8 earthquake broke out. The team kept the camera rolling as they moved through the crowded streets, surveying destruction to homes and historic sites and capturing scenes of heroism and chaos.

The Nepali Pranksters’ videos show people’s reactions to various “pranks” that challenge cultural norms. One video shows the pranksters walking up to strangers and taking their hands for a long, awkward, handshake; another shows them complimenting men and women on their clothes and appearance, with mixed results.

For their next prank based on Nepal’s ban on plastic bags, Ashish Prasai and Akash Sedai were in Jawalakhel, Sedai said in an email to CNN. The town, in Lalitpur District, is home to Nepal’s famed Central Zoo.

The camera was rolling when they felt the ground shaking around 11:55 a.m., Sedai said. People started screaming and crying and vehicles came to a standstill as a building collapsed in the background.

But earthquakes are a fact of life in Nepal, and “we were still thinking it was a just a simple earthquake,” Sedai said.

They kept the camera rolling for 18 minutes as they traversed the streets full of crying and shouting people. They found homes destroyed, where people were pulling survivors out from piles of rubble. They stopped and talked to motorists, urging them to keep the streets clear for emergency vehicles, Sedai said. (CNN)
