                                    Orientation effects are believed to be important in sources which harbor
relativistic jets in their nuclei. BL Lac type objects are interpreted
as a type of this class of objects whose galaxy counterpart is a bright
elliptical galaxy. This interpretation requires every bright elliptical
galaxy to have a BL Lac type nucleus beamed usually away from the
observer. The possibility of identifying M87 as one of those misaligned
BL Lacs is discussed.
