While I was in college in the early 70s, a fraternity mananged to have some of their members impersonate Tech ROTC students who managed to 'retrieve' Harvey (called by TTU 'shinny ninny') from the Tech bookstore where it was on display for publicity photos at Overall Field that the students claimed the tech sports department wanted. It was taken back to the Middle Tennessee campus and was great publicity for the college all week. At the end of the week, a delegation of students from Tech traveled to the 'boro' to receive back the totem pole but had to wait while MT students put on pep rally of MT students gathered at the Cope Administration Bldg. The week was capped off by a road trip for MT football to Cookeville where it lost for the 5th straight loss for MT in the series.
In 1980 or 1981, TTU students faked a seizure in the back of the Bookstore.... In the confusion, other's removed Harvey and took it to Cookville...
A couple of weeks later, a call was received stating the location of the totem pole in Cookeville. Several Sigma Chi's took off to get it.... After searching several fraternity houses (it was 10 in the morning and they were in class), they dejectedly started back to the Boro. On their way to the Interstate, they kidnapped the Eagle mascot from a fast food restaurant and took him to the Boro....
Long story short....
Harvey was returned and has never left...
