Procrustean or procrustean bed.
Procrustes (the "one who stretches") was encountered by Theseus. He would make unwitting travelers lie down on a bed. If they did not fit it exactly, he would either cut them down or stretch them out to size. The adjective procrustean refers to someone or something that aims at conformity through extreme methods. A procrustean bed decribes a terrible, arbitrary standard against which things are measured.
