The reason college cafeterias do that it because when food is made in huge batches the way cafeteria food it made, they run the risk of something going wrong that could possibly make the eater sick. They put laxatives so that it will get out of your system as quick as possible just in case there is indeed some food poisoning problem. Sick, I know. (no pun intended)
"This is what I trained to do, and this is what I love about theater. What I love about being an actress is being able to really look into myself and understand another human being. And out my own self, to shape and form and fashion a real human being--and to present that in such a way that people see something of themselves or their own understanding in that human being."
