Fast as F*** party food ideas - go!

We're going watch the parade in front of a business on Main Street in Houma. The business is owned by some friends of the family. They let us use their restrooms and there's food out for everyone. Although no one would say anything if we didn't, the sort of unspoken rule is bring something for people to eat/snack on.

I've only got a couple of hours (if that) before they start blocking off roads. There's nothing in my house except fruit and vegetables.

Only things I can think of are go pickup some Popeye's or pizza or something like that.
