About three hours into the game, after you pass the cold storage part, you 
will end up in a
hallway with a lot of doors you can open. The middle door will have some 
computers and
an enemy that never heard the gunfight because he is watching a television 
with some
headphones. Kill him and the television will be yours to use. The option to 
change the channel
will be given to you. Change the channel and some music videos and cartoons 
will pass.
Wait a few seconds to see what is coming on next. There will be one with 
some cheesy music
and words, and white lines coming out. This is actually a movie from 1955 
called The Man
With The Golden Arm starring Frank Sinatra. You can watch the entire movie 
on this television.
