I assume most folks have a container in which they dump their pocket change. I do. I use stadium cups like those you get at sporting events. I collect change in them over the course of a couple of years (generally filling several cups to over flowing).
I call it my "party fund." When I cash in the change for bills, I then use the money for some alcohol fueled indulgence.
I'll be cashing in the cups this weekend. I hear there's this bar that will give you a t-shirt if you do a shot with a worm in it. I'll be getting at least one t-shirt with the party fund. WOOT!
