YouTuber Jillian Haker has spent an entire year pulling the same prank on her brother over and over again... And he falls for it every time.
Pretending to take a Snapchat selfie, she actually records a video of him posing, capturing the moment he realises every time.
It's understandably frustrating, so there's some strong language.
In the description, Haker says: "The ultimate goal would for this to go viral so I can meet Ellen... Or Taylor Swift. Just throwing that out there."
