One funny story is about an older gentleman with ADHD. He was constantly misplacing his glasses. One day, he searched everywhere in the house. Finally, he found them on his head. He had been looking for them for hours while they were right there all along.
A grandpa with ADHD was trying to tell his grandkids a bedtime story. But he kept jumping from one plot to another. He started with a fairy tale, then suddenly switched to a story about his fishing trip, and then to a memory from his childhood. The kids were so confused but also found it really funny.
There was a middle - aged woman with ADHD who decided to bake a cake. She got distracted by a bird outside the window halfway through mixing the ingredients. She ended up adding salt instead of sugar because she forgot what she was doing. The cake was a disaster but it made for a hilarious story later when she told her friends.
