Richard Feynman said he often misled people to think he was irresponsible and couldn't be trusted with admin work for the students in the university he was teaching. It's not that he didn't care about the students (he did) but he thought his time was more valuably spent on physics. So he simply misled the folks who WOULD bother about admin.

Today I had a Richard Feynman moment and don't know if I was relieved or disappointed that I could be thought of as irresponsible.
