- Stephen and Mal's apartment
Stephen goes to the dentist today, and the dentist calls him out on his lack of flossing. To help himself get into the habit of flossing, Stephen issues the official StephenVlog Flossing Challenge™! He invites the viewers to join him on his quest to floss every day for the next six months.
- A similar challenge was in April 2011, where Stephen challenged his viewers to avoid drinking soda for several months.
