This thread loosely reminds me of that classic scene in "Annie Hall" - sharing just for smiles.
Alvy Singer : [the man behind him in line is talking loudly] What I wouldn't give for a large sock with horse manure in it!
Alvy Singer : [to audience] Whaddya do when you get stuck in a movie line with a guy like this behind you?
Man in Theatre Line : Wait a minute, why can't I give my opinion? It's a free country!
Alvy Singer : He can give it... do you have to give it so loud? I mean, aren't you ashamed to pontificate like that? And the funny part of it is, Marshall McLuhan, you don't know anything about Marshall McLuhan!
Man in Theatre Line : Oh, really? Well, it just so happens I teach a class at Columbia called "TV, Media and Culture." So I think my insights into Mr. McLuhan, well, have a great deal of validity!
Alvy Singer : Oh, do ya? Well, that's funny, because I happen to have Mr. McLuhan right here, so, so, yeah, just let me...
[pulls McLuhan out from behind a nearby poster]
Alvy Singer : come over here for a second... tell him!
Marshall McLuhan : I heard what you were saying! You know nothing of my work! You mean my whole fallacy is wrong. How you got to teach a course in anything is totally amazing!
Alvy Singer : Boy, if life were only like this!
