We do, but it's easy for whimsy to go too far. Googly eyes on a poster is cute. Graffiti everywhere isn't.
When one person does it, it's a clever surprise. When many people do it, it quickly becomes tedious and repetitious. It's interesting only when it's done judiciously. It's even worse when it escalates, such as with vandalism, or cruelty, or shock. And one person's "whimsy" can easily become "what, can't you take a joke?"
So I can see why an HR department would want to say, "Yes, the was very cute, the first time. Please don't turn it into a problem".
