1) Target: Jimmy Olsen! (As a science geek, I just can't vote for TEHI, which, in my book, was worse than the Ides of Metropolis, which I couldn't stand either "My LAN isn't talking to my A drive!")
2) Tempus Fugitive (Have you seen my avatar???)
3) Top Copy
4) Return of the Prankster (I like him, too. Oh, a fanfic with both Tempus and Prankster...)
