Most of the time, our lab lights were on long into the night. The inlays helped us get the clearance to get building and lab access 24/7, unlike most other departments. Ten of us were undergrad assistants and had keys to the building and most of the labs and classrooms (not offices or most professors' research labs, unless you were directly involved in that research). It helped us all in the long run.
It all tied in with the major (Geology), you could drink the occasional beer and knock about on the rocks, too. Moderation was the key, educate more brain cells than you kill...
I knew a guy in on a golf scholarship (4-year ticket) who managed to drink his way out in a record two semesters. Unreal.
