I would love it to be a humiliating surprise, each item more gross than the last. Alternate between sweet and savoury things, making sure that the next one clashes with the previous. Make it nasty.
Not super important to me either way. Biggest benefit, in my opinion, would be if someone is being humiliated with a range of unknown gross things. Of course, you can't plead and express how much you hate beans if you don't know there's a can of beans above your head.
