I don't want to have dinner with any of them. The thought of having to sit there and listen to Arnold talk about himself for several hours might be enough for me to pull a Joker on him.
No but seriously, I really don't see the point of having dinner with some actor or athlete just because I find some of their work entertaining. Sure, their work influenced my life, for better or worse, but that stuff is larger than any of them anyways. If I was an actor or filmmaker, then sure, that's different, but as a fan and not a fellow professional in that line of work, not thanks.
I'd rather have dinner with a historical figure that's been long gone out of curiosity to see what they really looked like or sounded like in real life.
