Stargate: SG-1: Three Ways Jack O'Neill Will Never Appear on TV and One in Which He Will, by
Workplace Legends, by
Harry Potter: Harry Potter and the Bookwyrm, by Jelsemium. Harry gets trapped with a riddle-asking snake in the library. Rescuers proceed to get trapped with him. The story has all the elements of something that could be funny, then falls into maudlin musing. Erk.
Crossover: Given Up, by Yahtzee. X-Files/X-Men. Mulder finds the X-Men and asks them whether his and Scully's child may have been a mutant instead of a possessed alien. Sad.
Been There, Done That, by Martha Wilson. Stargate SG-1/Hercules. Fun stuff here, but the author's name ought to be a tip-off. If you don't know who she is, for shame. Jack accidentally kidnaps Iolaus. Hercules wants him back. The culture shock is the funniest part, but one of Martha's stories is always interesting.
