Yes! Not only a blanket apology, but a preemptive blanket apology!

"I, Bee-dubya-ell (aka Bruce, Bee-dubs, Beezer, Asshole and various other things), do hereby apologize to anyone who feels they have been offended by anything I have said at any time, past, present or future, upon this fourum. Those who feel offended are instructed to read this message and then piss off!"
