What can we do for our open mic host on his last day?

Our open mic host will be graduating in May. He has been hosting our Union's open mic for 2 years. What's something the regulars could do at our last open mic with him to show our appreciation.

The more specefic the better.

Thanks!

create something for him from everyone like a song or poem or something! and make everyone go up and Mic it!

Have a party for him. Cake, pizza, pop. Give him a gift card and a plaque for his service!
