Hee! I've always thought that if Johnny and Fraser tried to hook up, Fraser would say, "You know, you rather remind me of my ex-partner, a police detective from Chicago."

And then Johnny would squint at him and grin, and say, "Well, for that matter, you're an awful lot like my nephew. It's kinda spooky. Come on, you should meet him." And that would be that.

I mean, you can't get nekkid with someone who reminds you overwhelmingly of your nephew, right? ;-)
