What are some interesting proxy/attendance stories at IIIT Allahabad?

There was a guy Tarun Agarwal of the Electronics Branch and a faculty, Shirshu Verma. I heard this story from a friend. According to him, no one knew what kind of bond these two people had. Looking at them together, nobody could distinguish who is the teacher and who is the student.

Tarun never attended Shirshu Sir’s classes but he had 100% attendance. Usually, some of the other students used to make a proxy for others. When nobody used to make a proxy of Tarun, then he used to mark his attendance. And this happened not once or twice but frequently. In fact not only attendance, but he also used to give him full marks in all his subjects. There might be some secret of Shirshu Sir that only Tarun knows. Most of the batch used to think so. 

There are endless proxy stories in engineering batches and every story is better than the other.
