A man walks into a bar and orders a drink. The bartender hands him a glass of water and says, "Sorry, we're all out of alcohol."
The man looks disappointed but takes a sip of the water anyway. Suddenly, he starts laughing uncontrollably.
The bartender is confused and asks, "What's so funny?"
The man replies, "I just realized why I came to this bar in the first place. I was hoping to drown my sorrows, but now I'm just hydrating them!"
