What have you done for your DM/GM at the end of a campaign?

I'd like to do the same, but I'm not going to be able to do the book - I'm thinking of a t-shirt with some of the campaign art from the APs/modules. It is an almost 10-year campaign.

"I survived [DM's name] 10-year campaign and all I got is this lousy T-shirt"

alternatively,

"I had to put up with [player] for 10 years and all I got is this lousy T-shirt"

After a campaign ending TPK we'd take the DM out back and give him his presents.

Literal laugh out loud (spouse looking at me side-eye - explanation needs too much antecedent context to be worth the squeeze - I accept side-eye)

We tell them "leave the head of the table and let someone else DM." Unless he is running the next game.
