Principal Investigator Coffee Mug

The laboratory PI has much in common with a mummy or a daddy and should learn to use this handy phrase early and often in dealing with the unending infernal barrage of questions from simpering graduate students and postdocs. Why won't you pay for our conference registration? Why do you get to fly first class and we have to hitchhike? Why do you get to stay at the Ritz and we have to sleep at the bus station? Why is your poster professionally printed and ours are made out of napkins and shadow puppets? Why do you take summer salary out of the grant and we have to get part-time jobs? Why? Because I'm the PI, that's why. Easy peasy. Pub domain smarmy scientist clipart from the nice people at Clkr.com. Text is customisable, so you can pretty much have Mr. PI there say anything you'd like.
