If someone who feels offended by swear words would not fit your company culture, perhaps you should keep it.
Agreed. I often make it a point to swear in an interview to gauge the candidate's reaction. If swearing offends you, you wouldn't make it a day on our team. Not saying it's right, it's just the truth.
To the contrary, it plainly expresses to me (a pottymouth) that I wouldn't have to spend considerable effort in watching my every word while amongst my peers.
I'm perfectly willing to mind my Ps and Qs in the presence of clients, but I prefer a culture in which I can let my guard down somewhat to my co-workers.
If that is not the case, then by all means, delete it.
