Sure. There was this one time when a guy took a diuretic before a long road trip. He kept having to stop every few minutes to pee. By the time they reached their destination, his friends were all teasing him non - stop about how he was like a little kid with a tiny bladder.
Once, a patient was prescribed diuretics. He didn't quite understand how they worked. After taking them, he went to a movie. But he had to get up so many times during the movie to use the restroom that people around him started giving him dirty looks. When he found out later it was because of the diuretics, he couldn't help but laugh at his own ignorance.
Well, I heard about a woman who accidentally took double the dose of her diuretic. She ended up running to the bathroom so often at work that her colleagues thought she had some sort of strange exercise routine. She finally realized her mistake and it became a hilarious story she told everyone later.
