At CU-Boulder we have a senior chair who spoils us all year long. There are things like senior/new member dinner, spoil a senior week, etc. At the last fun meeting in May we have a senior roast where 2 undergrads buy presents and talk about their favorite memories with each senior...it is both hillarious and so sad. Finally after a senior gets roasted they pass out old t-shirts from previous years and events to undergrads. A lot of the time no one wants to part with their t-shirts, so my class started getting 2 of each one!
