This story ruled. You rule, for telling the story, and for being its perpetrator.
Here's what you should do -- get whatever bag you want, then make a stencil with the LV logo, then get a can of spray paint that will paint in as fine a line as you can, and spray "FAKE" on it in big bold letters. EDIT: No, even better idea, "NO REAL THAN YOU ARE". Or perhaps just, "LEGO".
I would so like to do that. In fact, now that I've thought of it, I may just have to do that.
Except, of course, in all black -- black bag, black stencil, black spray paint. I know just the bag I'm going to start with, too. (I already have it. It was part of a 4-piece set I got at CVS for $25.)
