Meetings - such a waste of time

I can't believe i just spent 3 hrs in my office today, being in a meeting, to which we were called, to discuss something which we received as an email just yesterday. What a waste of time...I mean seriously, i sometimes feel managers are so jobless that just to show other's that they are working, they call for meetings. After all we are engineers, not some dumb brainless animal which needs to be fed with the same information 2 - 3 times. I can't show u my frustrations and inner struggles in the meetings, but i can atleast show u this dilbert strip which amazingly depicts the same situation, but handled in a much cleverer way...i think i should try this sometime...
