it's a tie between _floyd and Seneca.
While Seneca can be a smart ass most of the time, he's a good dude, and I enjoy talking to him. I think we have a good bit in common, being the same age and all that.
_floyd is the funniest guy I've probably ever talked to, as he's so quick witted and spontaneous. He's a bit older than me (and that's OK because I'm legal) but he's got the coolest personality.
I really don't care where the dinner takes place. I'd probably be fine if _floyd just cooked, because he knows his shit.
Of course there's a lot of others I want to have dinner with, but these are the two I talk to the most, nearly every day.
