:-)  It's not the difficulty of understanding laziness that I find embarrassing.  My Ph.D Computer Science friends that I have introduced Haskell to understand that very well.  It's their "You've got to be kidding" looks when I tell them they have to call 'length' for effect or some such to get their simple programs to work.  They understand Lazy IO and think that it is broken. :-)
