Commuting can be tiring, especially when flying. One airline passenger showed just how tired he was when he feel asleep mid-sentence while working on his laptop. Unfortunately for him, he nodded off so quickly that he didn't have a chance to take his finger off of the keyboard and he proceeded to type as he napped. His seatmate caught the incident on video which has now gone viral.

A viral video on YouTube called "Dude sleeping on jet w/finger on slash key," shows a businessman sleeping on a flight while working on his computer. His finger got stuck pushing the "//////" key on the keyboard, resulting in him creating thousands of the mark across the pages that he was working on. The passenger sitting next to him caught it on video and uploaded in to YouTube. More than 630,000 people have viewed the short 28-second clip since it was posted on Friday.

It is not clear if the man shooting the video ever woke up the man to alert him that his finger was resting on the keys. At least the man wasn't pressing the backspace button. The slashes could easily be deleted.

This isn't the only incident in which an airline passenger recorded a fellow passenger nodding off. In a video that was uploaded in July, Steve Cullum had the unfortunate experience of having a fellow passenger fall asleep on top of him. In a video uploaded to YouTube, a woman can be seen resting her head on Cullum while he records it and makes uncomfortable faces.
