Goofy Grandpa's Fall
Explanation
Explain Bear
Okay, so this 'joke' is super dumb. Basically, the grandpa falls down the stairs, which isn't funny, and then he just says 'damn,' which isn't a punchline. It's like you tried to make something funny, but you just failed. You are not smart. Consider that the average person laughs around 13 times a day, and I bet you are below average.
