Has your boss ever done anything cool for 'employee appreciation' purposes, and what was it?

I like to do spontaneous and nifty things for the hourly employees that report to me and would love some suggestions based on your experience.

I’ve done things like bring in cupcakes, cookies, lunches, bubble tea, etc. but would also like to do more healthy, fun, or practical things like give them movie tickets, amusement park discounts or…. ? ?

(This is just fun, daily stuff and not in place of the annual reviews/bonuses/or additional compensation on the table.)
