It's probably completely made up, but I can't find a fault in its factuality: a bar graph showing virginity rates upon graduation. That's not just any virgins, though: this is a chart for Wellesley, a private womens college. Art majors bottom out the extreme end at zero graduating a virgin. Duh, the virgins all realized their sophomore year that an art major doesn't pay well, and switched to an Economics major. On the other end of the chart, are, unsurprisingly, math majors - so, take a wild guess the major of the person that spent a Friday night making a gradiated bar graph instead of fucking some drunk guy on their roomates' loft bed?
