A Youtuber spent more than nine hours holding his finger on a button, not even going to the bathroom, because he wanted to find the end of Microsoft Excel.
Nobody claims to have been to the end of the program's spreadsheet and it has been deemed endless.
However, Hunter Hobbs, a graduate from Oklahoma University, went out to prove he could go to the last row in a challenge he called "the dumbest ever".
Mr Hobbs prepared himself with water and a banana and pressed his finger on the down arrow key for as long as it would take.
“I don’t know how I am going to use the bathroom,” he said in the video.
“But the challenge is I have to keep my finger on 'Ctrl' and 'down' until I reach the bottom, or I lose.”
In the clip, Mr Hobbs sits at his desk and passes the time by reading books, listening to music, talking on his mobile, listening to music and eating.
Mr Hobbs switches his fingers without lifting the key multiple times throughout the fast-tracked video.
He apparently did not even get up to use the bathroom.
It took the Youtuber nine hours and 36 minutes to get to the end of the Excel spreadsheet, which it turns out contains 1,048,576 rows.
"I'm tired, I'm hungry, my hands really hurt," Mr Hobbs said.
"Please don't do it."
