arbitrary thumbtacks on maps.google.com

Does anyone know how to get Google maps to locate a thumbtack at an arbitrary point on a map? I recall directions from Brevity on how to get it to draw an arbitrary route, which is a nice touch, but I’d like to be able to say “The thing I am talking about is HERE” and have a precise thumbtack regardless of availablilty or precision of street numbering.
