The NYPD recently reminded New Yorkers to avoid snoozing on subway rides.

“If you are sleeping on the subway, you make yourself a very easy victim and much more susceptible to a crime,” Police Commissioner Bill Bratton said last month. “Why would you put yourself at that risk?”

Now it seems there’s another compelling reason for straphangers to avoid dozing off: rats who might mistake you for a cuddle buddy.

3AM on the 7 train. MTA subways come equipped with cuddly rats. #mta #goingyourway #nycsubway A video posted by Antony Lin (@copaantl98) on Mar 27, 2016 at 2:21am PDT

In a video that’s gone viral this week, a man sleeping aboard a 7 train in Manhattan was shown being awakened by a rat -- after the rodent decided to get a little cozy.

“I started filming because I’ve never seen a rat in the car before,” Antony Lin, who shot the video around 3 a.m. on Sunday, told ABC News. “Just to see it was shocking.”

Lin said the rat “roamed around for a bit” before moseying over to the napping man. The rodent managed to climb all the way up to the passenger’s neck, before the man awoke with a start.

“He screamed and ran into the next car,” Lin told ABC News.

Some netizens criticized Lin for filming the encounter rather than trying to help the man. Lin, however, defended his actions, saying he was wary about waking a stranger at such an early hour.

He also said he hoped the video would encourage city officials to do something about the subway's rodent problem, which is apparently a citywide issue.

“It's just insane and disgusting...” Lin told NBC New York. “I've seen [rats] on the tracks and platform, but never inside the train.”

Lin insisted that the video was not the result of a practical joke, but as Mashable pointed out, one can never rule out the possibility of Zardulu involvement. (Zardulu is the rat-training, Brooklyn-based artist believed to be behind such viral videos as the “Selfie Rat” and the “Three-Eyed Catfish.”)

The artist herself tweeted this on Wednesday:

You should never watch anything without thinking about Zardulu https://t.co/UN9PGbwevw — Zardulu (@iamthemythmaker) March 30, 2016

Still, it seems the story of a rat interrupting the sleep of a commuter is not new. As Gothamist noted, a video captured a similar scenario on the subway in 2011.
