Tattoos in the Workplace I'm an undergraduate mathematics student finishing my degree.  I plan to go to grad school, and ultimately aspire to become a professor.  I really like tattoos, but I'm hesitant to get one because it could affect my future job.

Of course, if I did get one, it would be discrete and innocent.  What I really want is the axioms from ZFC wrapped around my upper arm.

I'm very interested in hearing people's thoughts on tattoos in the workplace, particularly from people who work in mathematics.  Do you think it is acceptable?  How would you judge someone based on their tattoos?  Do any of you have tattoos?  What are your experiences?
Tattoos that can be easily concealed in sensitive times (during interviewing, etc.) should never be a problem. Further, academia is in general a pretty tolerant place when it comes to looks. As Suresh says, we are used to much weirder things in terms of look than a small tattoo. You'll be fine.
