Life for me is a paradox and what more can be more fun than using Oxymora. An oxymoron is a figure of speech in which words that seem contradictory appear together to form a fun combination. Some of my favorites are Military Intelligence, Original Copies, Exact Estimate, Old News,Living Dead, Deafening Silence and my personal best is Microsoft Works, :D
Here is a link to some really good oxymora......
Another O I like is a bollywood song called Ooh La la la (you dont have to understand the lyrics, just enjoy the music).
