Best reaction ever to the discovery of slash came from Paul Gross, I think, who was informed about it in during an interview about taking over production for a new season of Due South. Said interviewer then went and found some for him. He promptly laughed himself sick, said that if the fans had managed to find that much in the original series, that they'd positively wet themselves over the new one, especially since the new guy was really good looking. He then went and essentially wrote it into the text, getting about as close as he could without actually being obvious about it. (The behind the scenes stuff is very ... illuminating. Especially the bits where they start humping against the wall while in character.) Eventually, they ride off into the permafrost together to end the series.
