I am obsessed with CHUCK(best thing ever).
Currently I also like Superman/Wonder Woman pairing but CHARAH remains my absolute favourite pairing.
Fav Pairings : CHUCK/SARAH, House/Cameron, Superman/Wonder Woman(I know last two are non canon, but they belong together).
For CHUCK/SARAH lovers...you guys should read fics by these authors - Wepdiggy, BillAtWork, sdchuckfan, Notorious JMG and frompen2paper. They are absolutely fabulous.
ANY OTHER PAIRING OTHER THAN THOSE STATED ABOVE ARE BLASPHEMOUS, SACRILEGIOUS, DISGUSTING...
Anguished by those authors who leave their stories incomplete or take ages to update.
