Is there a way to say/write something when you, really, don't want to say/write that something?

That sounds a bit cryptic perhaps, but i mean the following:
Earlier i saw this question about cats licking their humans, and i was tempted to write something in the lines of; “He, i am surprised that nobody has said something naughty about cats licking their human.”
But then i would have been that somebody myself and i didn’t want that, if you get my point.
So, is there a way to get around that ‘dilemma’?
How writers that do that?
