All you with penises stick together

I'm not mad or angry and it's really just a big joke between us but I really want some opinions here! This is not something that has caused relationship stress, I swear!

I had two DVDs in my hand. I held up the first one- Grosse Pointe Blank, starring John Cusak and Minnie Driver. The conversation followed:

Me: Have you seen this?
ITSam: Oh yeah. I love that movie. It's a great movie.
Me: cool. Let's watch it tonight?
Sam: Okay, sounds great.

I hold up the second movie- Beautiful Girls starring Timothy Hutton and a bunch of other people (Natalie Portman, Rosie O'Donnell, Mira Sorvino, Matt Dillion, Lauren Holl, Uma Thurmon)- and I said:
Me: And this one?
Sam: Oh, I don't like that movie.
Me: Oh really? Why?
Sam: sits there and make icky faces
Me: Oh com'on it's not that bad. it's got a great cast. Do you not like it because of Rosie?
Sam: uh, no. I just don't like it.
Me: The story is good, funny, a guy bonding thing and Natalie Portman's in it; you like here!
Sam: squirms in his seat
Me: wait, have you even WATCHED this movie?
Sam: Well, no but it doesn't look good.
Me: you said you saw it!!
Sam: Technically, I said I didn't like it, not I haven't seen it.

Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrr! Okay, yes that's what he said. Yes, that's what I said. But I contend that he lied and implied he saw the movie, sort of lying by omission. He says he didn't; he says he just didn't answer the question I asked and I assumed.

Yes, technically he didn't answer my question but he knew his answer would make me THINK he saw the movie. Stuff like that drives me batty, mostly because it's such a high school student conversation!

I asked two other males their opinions and they side with ITSam. Men...!

By the way, is the plural of penis "penises" or "peni"?
