An unusual video has emerged of a man brushing his teeth while on the London Underground. <br /><br />In the footage, filmed this week, the man in a green jacket can be seen scrubbing his teeth furiously with a plastic toothbrush, while a tube of toothpaste sits on his morning coffee. <br /><br />It's unusual to see someone brushing their teeth on the Tube, but anything's possible on public transport.<br /><br />The filmer later wrote online: "I found this brushing his teeth today whilst commuting in the London tube. As soon as he left, everyone bursted out of laughter"
