The worker in Brisbane thought he had the office to himself, deciding to liven up the end of the day.
Unfortunately for him, the office block behind him saw everything, with one posting a picture on Twitter, gaining 2,000 retweets.
Twitter user James P, with the handle @PenguinShepherd, also tweeted a series of updates on the mystery man.
Luckily for the unnamed worker, James chose not to include the office's location, meaning his boss is less likely to come across it.
James also decided against using his high resolution digital SLR camera, which he happened to have with him.
Finally, at the end of the day, the man realised he had been on display the entire time. When he realised he was being watched, they gave him a round of applause.
