OO Inheritance

Object Oriented Programming Inheritance. Is there even a point to it? Every time I see people try to explain it they always use that fucking "Animal", "Dog", "Cat" example. I'm honestly not seeing the benefits here. Can someone give me a practical example?

That's funny, because I've found that the dark side of inheritance is most obvious when trying to write a GUI. Teetering your way through some kind of stubbornly linear widget phylum is not just aggravating, but a blatant case of hammering a screw.
