Something really weird I realized last night...

Isn't it a little bizarre that between Ben and Vivian, they never bring up the Rubber Man, especially after she had sex with him? I just thought it was weird that this conversation never happened:

Vivian: Wow. You fucked me so good last night! Ben: ...what? Vivian: You know... You put on that black rubber suit, got on top of me... Ben: No I didn't. What the hell are you talking about?

and so on and so forth. I don't think anyone's ever had kinky sex and NOT brought it up at some other point in time.

I realize I'm looking at a completely fictional show realistically but this just kind of bothered me.
