Parents have been able to put their three children through private education - after YouTube paid them £100,000 for their homemade clips.
Howard Davies-Carr, 42, is the dad of Charlie and Harry - who became famous through the 'Charlie bit my finger - again!' video originally made for their godfather.
Since he posted the clip on the video-sharing website it has been viewed more than 387 million times. The family are paid for footage that goes viral.
Mr Davies-Carr, who now posts videos every six weeks and runs a website, said: "Nearly all income from YouTube is banked. A little is spent on holidays and we bought a castle for the garden.
"We would have struggled to put all three boys through private education but with the YouTube money we decided to commit to all, and it was always going to be all or none."
The deal is a type of partnership that sees YouTube split revenue from advertising running alongside videos with users.
The IT consultant, from Buckinghamshire, is not the only one to make extra cash. Jamie Hagan, 18, has raked in £40,000 in three years by posting hilarious footage of his 11-year-old brother Jacob.
