Personally, I have had best compression success with Microsoft's CAB compression. Is there any BETTER compression?
A guy gets on a bus and starts threatening everybody: "I'll integrate you! I'll differentiate you!!!" So everybody gets scared and runs away. Only one person stays. The guy comes up to him and says: "Aren't you scared, I'll integrate you, I'll differentiate you!!!" And the other guy says: "No, I am not scared, I am e to the power of x."
