BOZEMAN, MT—Lakecrest Elementary School teacher Dana Frankel bitched to her sixth-graders about her "crap salary" shortly after receiving a paycheck Monday. "How am I supposed to pay for anything on this kind of income?" asked Frankel midway through a math lesson. "And now the brake pads on my Nissan need replacing. Gee, guess I'll just have to hope for the best next time I hit a red light." Frankel then got the disrupted lesson back on track by using her dwindling 401K plan as an example of negative numbers.
