Lynn S. of Reflections in d minor objects to people who say 'concertos' and 'cellos' instead of 'concerti' and 'celli' (scroll down to the second-to-last paragraph). If she wants to tease such people in person, she can always serve them a nice meal of veal scallopinos, with broccolos and zucchinos on the side and maybe some pennas or rotinos for the pasta.
