The McDonalds one 'Try Our New Crap' is probably the most honest one.... instead of driving thru you drive by.
The Subway 'free napkin w every purchase' is a joke, though. Here in Oz we can help ourselves to a handful of napkins at Subway and other fast food outlets. McDonalds can be a bit tight fisted, though. You'll get a napkin per each meal on the tray, but if you need more you have to ask in most McDonalds these days.
