When you see Jack walking with Janet and Terri in the closing credits he has the look of a guy walking with two girls he is having sex with or dating period right in front of the landlord who believes he is gay:lol:

I can't even picture myself walking with my arm around my platonic female friend. So that's why the closing credits always looked weird

Well you're a straight guy so how are you to judge what a gay guy would do? lol I think friends who are really comfortable with one another do that no matter if they are straight, gay, etc. And on this show everyone is very demonstrative and affectionate with one another, so I don't see how it doesn't fit.

And anyway, I'd like to think Furley didn't care that much deep down whether or not Jack was gay. They all became such good friends (really, Furley's ONLY friends) that had it come out for sure that Jack wasn't gay Furley wouldn't have really kicked them out.
