(this is becoming the Back to the Future thread).
Gawd, for Christmas about two years ago my dad and Mo sent me the Back to the Future blu-ray set (I had it already) but they included a picture of Mo with Michael J Fox and Stephen Pollan which blew my mind! They spoke at an event Mo was hosting. And of course, they hadn't seen "Curb" so I blew their mind by knowing who Stephen Pollan was.
