This is really very nice, but a shame about the swear word, which, I think, makes the whole thing feel a little tacky. I know this has been discussed to death but I can't help but cringe a little when I see something like that.
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.
