Really Columbia University?  Really?

'Professor' Vinnie Guadagnino was a guest speaker at the learning institution earlier this week.

The sociology department thought the 'Jersey Shore' mama's boy would make for a good example in how the laws of 'deviance' affect the dynamic in social settings.  Vinnie also spoke candidly about being the victim of  bullying during his own school years.  Things seemed to be going swimmingly until the evening's question and answer session, when a student asked the reality star what gave him the right to interrupt an important lecture...an inquiry that left Guadagnino at a loss for words.

Your Ivy League tuition dollars hard at work, lol.  The biggest lesson of the night?  STAY IN SCHOOL.
