I spent an alcohol-drenched year at Dundee University, which had adapted a couple of traditions from when it was part of nearby St Andrews. The first was Gaudie Night, when as a 'Bejant' (fresher) you were 'adopted' by a more senior student who was supposed to take you under their wing and show you the ropes.
Your senior had to start by showing you hospitality, which involved buying all the drinks for the night. The downside was you had to drink whatever was put in front of you and some of the concoctions they came up with would probably be classed as biological weapons.
Anyway, if you survived that, after six weeks, they were released from their stewardship on Raisin Monday. You had to give them a gift (usually half a bottle of whisky) as a token of appreciation for them looking after you. In return, you got a "receipt" which was anything their twisted imaginations came up with. And you had to schlep your receipt around from 9am to midday, including to lectures.
I got away with it quite lightly, with a rusty bike frame with beer cans tied to it but some poor sods got the works. One got a cast iron bath tub, another was togged out as a french onion seller (complete with a string of onions round his neck) but the star prize went to the guy who had to dress as a country yokel, complete with a real, live goat.
The goat shat in the middle of a Physics lecture, which caused a literal and metaphorical stink, with arguments raging about the use of live animals as receipts.
