Google founders Sergey Brin and Larry Page paid a surprise visit to doctoral student Jacob Ritchie at his office at Stanford University.

Richie currently holds a PhD in Computer Science from Stanford University and occupies the old Larry Page office at the University. In a tweet on Twitter, he posted a picture Friday evening showing Google's founders visiting his office.

"Larry and Sergey are visiting Stanford" on a remembrance trip "after they stepped down on Tuesday from their roles in Google and Alphabet," Richie said in a Tweet.

Bigg and Brian met in 1995 while working on their PhD in Computer Science at Stanford University, and at the same time founding Google that started in 1998. The two founders announced they stepped down from their roles in Google and Alphabet Inc. this month, yet they remain one of the two richest people to The planet.

While Ritchie was working late in Big's office, the two knocked on the door to look at the place where they first gathered them without knowing he was there.

According to Richie, Bigg at the time acquired the office after Brin "illegally" gave him the main key to the building early, which allowed him to choose the best office.

Richie said the surprise visit was "an incredibly surreal and surreal experience."

One perk of being in the late office on a Friday is that sometimes you get surprise guests. pic.twitter.com/1rC08EmsoM
