It's an archetype of the American college student, the notion that their quest for knowledge is rivaled only by their quest for the free and the cheap: the two-for-one, the Thirsty Thursday, the all-you-can-eat.
When I attended the University of Minnesota back in ancient times, I had a list of the daily restaurant specials that ranged from the $1.99 breakfast to the occasional splurge on the $5.99 steak that was as tough as a calculus exam in Chinese.
Turns out I had it good.
According to a recent analysis, a U student in 1975 (before my time) could make tuition by working six hours a week at a consistent, year-round minimum wage job. Today, it's 32 hours by one recent calculation.
So it's no surprise that organizations and associations looking to lure students to events have taken notice of tough times and student appetites, plastering bulletin boards with offers of free lunch for a little face time.
And, in a sign of the times, it's also little surprise that a couple of brothers noticed the trend, and started a website to help their fellow students find a free meal.
Zoltan and Gregory Kiss (U.S.-born children of Hungarian parents) founded freefoodumn.com to offer a calendar of cheap eats for broke students. All you need is an indiscriminating palate, an open mind and a flexible schedule.
For example: "Dec. 7: Lunch and Learn, eat and learn about brain injury," read one entry on their site. "Cardiometabolic status in childhood cancer survivors, light lunch provided," said another.
