we havent had that much VC stuff at my school...
but one girl used ATM for her prayer in religion class once! and i played the cd during PE when it first came out.
but the stuff with my econ teacher was kinda crazy because he did all that within like 10 mins. i think i know where the Mary thing came from tho... cause the smallest girl in my grade is named Mary, so sometimes they call her "little mary" or "petite marie", maybe he was just teasing her by saying she was perfect, i dunno. or maybe there is some historical figure like that he was teaching about. cause he's also a history teacher.
