One of my pet peeves is misuse of percentages. When talking about personal effort or certainty or whatever, you can’t have more than 100%, can you? It’s just basic logic. One hundred percent is the most possible. You can’t give 110% because it’s more than it’s possible to give. If you can give more than you used to, it’s either because you weren’t giving 100% before or your capacity has increased. Make sense?
There’s a similar misuse that I really find revolting. People using higher numbers to say that they’re MORE sure of something than the other person. Example: “You’re 100% sure of it? Well, I’m 200% sure it’s not!”
The other day I came home from work and decided to see what was on TV, since I don’t usually watch it when I come home. I happened to hit the “Maury” show. The only thing greater than my repulsion of the show is my hilarity at the stupid people that go on the show! 
There was a paternity question (seems like that’s most of what happens on those kinds of shows, but that’s a topic for another day) and the guy said he was 200% sure the child was not his. Then the girl said she was 300% sure the child WAS. Then the guy said he was 1000% percent sure it wasn’t. I shook my head, lamenting both their lack of logic and their tragic lifestyles, and turned the channel.
