This is so funny. However, if Dilbert is so honestly worried about PHB having a lot on his mind, why doesn't he write him an e-mail listing the 4 things he needs. Whenever I want to talk to my boss (who definitely has more things to worry about than me) I write an e-mail first with at least listing the things I want to talk about.
1) Poor Dilbert ... what could he do about it?
2) "A case with four stones in it! Not one or two or three but four! Four stones! What the hell am I supposed to do with an empty case?" (c) Zorg in "The Fifth Element".
