I was wondering if using an animal headcover or funny headcover is just for kids in golf?

I want to put this funny gopher headcover or crazy looking dragon headcover on my driver, but I thought others might look at it too "childish"?
I mean I see pros do it.. i mean tiger does it too. haha. I was wondering if its okay for an adult to use interesting headcovers?

What is your opinion on this? If you use it, how is it and what are some expected responses? If you don't use it, what do you think about the people who uses them?
