Of course you can fu
cking curse.
In my defense of cursing, I present the following George Carlin quote:
I think the word fuck is an important word. It's the beginning of life, yet it's a word we use to hurt one another quite often. And people much wiser than I have said, "I'd rather have my child watch a film of two people making love than a film of two people trying to kill each other." I wish I knew who said it first, and I agree with that.
But I would like to take it a step further. I would like to substitute the word fuck for the word kill in all those movie cliches we grew up with. "Okay Sheriff, we're gonna fuck ya now. But we're gonna fuck ya slow..."
