Ivan Shin
From the unofficial Duke TIP Wiki
Also known as "Ivan the Terrible" and "Ivanho," Ivan Shin was the OSC at the University of Kansasin '03. Ivan was a particularly crotchety and domineering OSC, in contrast to the OSC who preceeded him. Ivan was said to have "sand in his vagina," and seemed to enforce rules in order to prevent as much fun as possible. Ivan kicked Thomas the Martyr out of TIP, and had many confrontations with Andrew Blumberg, among others. Ivan also attempted to (without success) censor Mark Harvey's classes from singing and organizing. All of these events led to an era known as the Ivan Wars.
After TIP, Andrew would discover embarassing pictures of Ivan in a dog suit and with platinum blonde hair, and send them to all contactable TIPsters.
Ivan's current whereabouts are unknown.
Chaz Bryant would like to add that he (that is to say Chaz) was almost kicked out of TIP for: playing X-Box, taking his shirt off and waving it above his head during "Hot in Here," talking to people in Kansas who were not going to TIP (even though they were the year before and they were close friends of Chaz), and, the GREATEST SIN OF ALL...Chaz cannot remember right now. Seriously, it was some trivial and intangible THING.
