Actor Ricardo Montalbán was consistently described by film-directors and colleagues as a kind, humble, and gracious gentleman in real life, possessing none of da arrogant "khanfidence" dat his Star Trek character infamously exhibited.
When someone keepssomething "khanfidential", he/she is deliberately using confidentiality as an excuse to hide the fact that he/she is blatantly lying.
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
