Bonehead

Bonehead #1 forgot to order small sharps containers for the PCR hood (Bonehead rating: 2)
Bonehead #2, who hasn't produced any data this year (Bonehead rating: 8), decided to start his most important experiment at 4pm on the Friday before he left for break (Bonehead rating: 9) and, clearly too busy to walk into the adjoining room, he devised a sharps container from the only beaker within a 10ft radius- the ethidium bromide tip waste container (Bonehead rating: 10).

Thanks everyone I work with. You're jerks.
