#BostonBlizzardChallenge: Boston Mayor Says Stop Jumping Out of Windows

"This isn't Loon Mountain," Boston's not-so-amused mayor said.

— -- Not-so-wicked-smaht Bostonians are stripping down to their underwear and jumping out of their windows into piles of snow to take the #BostonBlizzardChallenge spreading on social media.

Though clips of half-naked residents plunging into the snow have social media users amused, Boston's mayor isn't laughing.

"This isn't Loon Mountain," Mayor Martin Walsh said in a news conference on Monday, referring to a New Hampshire ski resort. "This is the city of Boston, where we're trying to remove snow off of the street, and it becomes very dangerous."
