I don't know of any traditions like that one, although I'm sure some of the colleges have their own. There are a few rules which seems bizarre - like immediate expulsion if you climb inside the statue (it's kind of like a vase) outside Senate House, or if you climb the exterior of King's Chapel. There are also things like if you turn up to an exam in full plate armour you automatically get a first class degree, and everyone in the room gets a first class degree if the Queen walks in during the exam.
