Scaring children for laughs is a staple of Internet culture, but did you know that your elders are also susceptible to fear? One man discovered that his father was very easily startled, and took advantage of the poor guy by creating a video compilation of his best reactions. This dad didn't disappoint, jumping in fear and swearing in his adorable accent every time.

Since the video was uploaded on April 21, it's quickly gone viral. Which raises the question: is it ethical to laugh at this man's pain? No, it definitely isn't. Now watch it again—we won't tell anybody.
