I've got a funny story - my BIL's girlfriend went to a baby shower and they were asked to bring a plate for afternoon tea, not sure if they were asked to bring sweets or if just coincidentally everyone brought sweets... but it turned out they had forty-five million cakes and muffins and sweet treats.

The host didn't want to be left with sweets to last her til 2020, so they had a "plate swap" and they all took home bits and pieces from everyone else's plates. BIL's girlfriend came home with some pieces of cake, a few muffins, some different slices and a handful of rumballs. Nice!
