Dennis Roady is an American YouTube personality best known for his prank videos which he posts on his YouTube channels Dennis Roady and howtoPRANKitup. His howtoPRANKitup channel has millions of subscribers and views. He wants to shock the world with his pranks, and help people with his good deeds. He was featured in the YouTube Red series Fight of the Living Dead: Experiment 88, in which ten YouTubers were placed in a zombie apocalypse condition. A born prankster, he caused a ruckus during the industry preview of a mobile app called Dude, your car! The app allows users to morph photos of cars and make them look damaged with scratches, dents, and clamped wheels or even on fire. Using the app, he played pranks on people and secretly recorded their reactions. When Dennis was hired by a Russian YouTube channel to review cars at the Detroit auto show, he couldn't let the opportunity pass by to play a prank with the same app. He made a three-minute video of it, which showed him fake-scratching a Mercedes-Maybach and Audi, and putting a fake dent on the side of a Dodge Challenger T/A Concept. The video earned more than 250k views within a few days. When he showed the image of the dented Challenger to a product specialist, she was immensely shocked, and ran to the car. Her reaction gave Dennis Roady more prank ideas. After the success of this video, he started working with Mobilaga, an app developer, to develop a new pranking app compatible with Apple and Android products.
