I'm probably going to be called a pervert, but I didn't find the canonical Cordnor (Cordy/Connor) pairing reprehensible like most people did. To me, it makes sense that Cordy would fall for Connor given her base personality and the fact that he IS Angel's son (had Connor not been around, I'm almost positive that AmnesiacCordy would have eventually realized/remembered her attraction to 'Mr. Tall, Dark, and Gorgeous in an Annoying Sort of Way' [as Buffy first described him to Giles back in WttH]). It also makes sense that she'd boink him (Connor), despite not knowing him very long (since she couldn't remember him, their interaction in Season 4 was pretty much new, at least to her).
Other Connor pairings that I find cool are Fonnor (Faith/Connor) and Cawn (Connor/Dawn).
