The credit-stealer:
Who wrote that report? "I was a huge part of the brainstorming process." Cut to brainstorming meeting- he's playing games on phone.
Who crunched these numbers? "Oh I was up all night with those." Cut to his all-nighter: sitting next to intern who's working while he snores away.
Who drafted that insurance policy? "I was monumental for that." Cut to him rollerblading by meeting room. Everyone inside watches, then says, "OK, so we should not cover random acts of stupidity."
