Dealing with the man who knows absolutely EVERYTHING?

and always has to tell you about it... we (my fiance and i) went to my dads work today to visit and see his new truck, and i mentioned as we drove into the parking lot and saw it, "i'm surprised he got black, he's never had anything close to black." and he said, "well have you ever seen me drive anything silver like my car?" i let that go, no big deal... then, i mentioned that i wondered why he didnt take the cargo rack off the back of the old truck and put it on the new one, and again, got a list of possible reasons why my father would do this... then, i happened to mention how much i liked my old pathfinder way better then my saturn... then i got a lesson of how foreign cars are so much better and thats where i lost him and made him stop.. i asked nicely, but i got my point across.. he tells me later that i pissed him off.. ugh.. the other thing is, last night, i stayed at his house because the weather was atrocious... tonight, it wasnt so bad, and i was gonna go home around 8:30, before this movie came on that he wanted to watch with the kids... he asked me to stay for the movie, because its more fun for everyone when im around.. so, i said ok... around 10:30, when the movie had a 1/2 hour left he says, "so, i dont mean to be a pain in the azz, but are you staying or are you going home?" so, i was like, whatever, went out and started my car.. when the movie was over, i left... i called him to tell him i was home, and when he asked if i was ok, i said, "yes, but for the record, i will never invite myself to stay at your house when your kids are there.. if you want me to stay, ask.. if not, then leave it... dont make me feel guilty..." and he was like, "again?...." and i said, "what do you mean, 'again?' " he says, "forget it, we'll talk tomorrow... good night..." and that was it... now, none of this he sounds like a jerk stuff... yes, he does sound like a jerk, on this day... but more often then not, he's really a great man... but how do i deal with his complete know it all- ness.... i can only yes him to death so much
