Bailey Quarters.
And yet you participate in discussions about Star Trek. 
But Morticia isn’t real.
Ethel Mertz. A very loyal woman who appreciates a good meal and owns a building on the east side where she could be my landlord. And if she really felt a need to be up to her ears in zany schemes I suppose I could help out with that too. 
Originally, I was going to say “Spock of Vulcan” but my love of women influenced my decision and, honestly, tying everything to Star Trek is a bit repetitive for me.
I think Bear Grylls would be a fun dinner guest. We’d invite him and the family over for a barbeque. Later, he could show us his slides and tell us hair-raising tales of his travels while we polished off the last of the Guiness. And the whole cast of Northern Exposure would make wonderful neighbors, I can’t think of anyone in the town I wouldn’t want to hang with. (we aren’t talking romantic attraction, I know, but I will put in Andy Travis of WKRP. Unfortunately he would always be uncommitting and working all the time and I would perish from the unrequited love. Never mind!.. Chase from House - I would be “that one special patient” that would make him dump Cameron. Tout Suite.)
Duncan MacLeod…there can be only one.
Well, the Clampetts have a nice house and don’t mind folks droppin’ by for a swim in the cement pond.
Doctor Who would be impossible to resist, though.
Which one?
Tennant, of course. 
If he brings Martha, I’m in!
I’m gonna say Jim Halpert from The Office.
And then for a female friend (with benefits?) I’ll take Liz Lemon from 30 Rock.
Because I like geeky, vaguely insecure people with a snarky sense of humor. (That’s why I hang out at SDMB.)
Ooh, I almost forgot about Methos. He’d definitely be high on my list.
I’d like to have a dog like Brian Griffin. If he actually became boring, like Quagmire suggests, which I personally doubt, I’d just tickle his tummy and get his leg going. For that matter, I wouldn’t mind babysitting Stewie – so long as I was “close enough” to get the gist of what he’s saying. I wouldn’t talk down to either of them, and it seems like they’d like that. Who wouldn’t want a talking dog and an 18 month old who speaks in complete sentences?
<sheepishly raises hand>
For my girl pick, I gotta go with (single) Pam from The Office (even though I would most definitely fall in love with her, she’d politely shoot me down, then our friendship would never be the same again).
For a guy…I dunno. How about **Cam **from Modern Family?
(but then, he’d fall in love with me, I’d politely shoot him down, etc.)
mmm
Kill them both.
Now, while you still can.
It is the only way.
The people who have replied Jim Rockford got the actor right but the character wrong: Bret Maverick is a legend of the west.
I second Sam Axe. Good guy to know if you accidentally get involved with any dubious characters.
Archie Godwin from the most recent Nero Wolfe series (just in case there were earlier); it would be fun to play poker with him, Saul Panzer, et al. I’d get to hear the stories about Nero Wolfe and maybe even get invited to dinner at the brownstone.
Or Velma Dinkley.
