Eek! Here’s one subway ride that will make your skin crawl.

The nightmare of every subway rider was caught on video after a chubby sewer rat crawled up the leg of a sleeping straphanger on a No. 4 train in Brooklyn and came face-to-face with the man.

The video clip, posted Wednesday on YouTube, has already become a viral hit and promises to freak out anyone who has ever taken the subway.

Rats are often relegated to the tracks as straphangers gaze at them while awaiting their train. This time, this rat-subway rider encounter was a little too close for comfort.
