It's a technique very used by some bosses (that dont know shxt). It's specially effective with young/big-ego !! developers. The modus operandi would be saying thay some work you did is crap. After that you provide a detailed report on the advantages of your work. And after that, he can tell his own boss what are the wonders he is acomplishing, all without reading a single line of the related documentation.

!! replace young/big-ego with any of these: ninja, guru, hacker, elvis, etc. :D
