Reincarnation

Slazy-the ignorant journalist was on the verge of being fired for his ignorance and laziness. To forget his blues, he decided to go to a local pub, where he found five friends bragging about how famous they were in their previous birth. Slazy thought that this will make for a sensational story about "Reincarnation of Famous Personalities" and will save his job. Being ignorant, he had no clue that the so called famous people were actually fictional characters only. He quickly scribbled the following notes about the first and last names of these five people, the "personality" they claimed to be and the reason why they were famous. He now needs your help to sort them out and create the "Reincarnation" story.
