I think I have most of the freebies from '09 and '10, but nothing since then. My favorite has always been the silver toaster. It was the first thing on Yo that I wanted really bad, and no one would send me one because they were higher level and wanted to send me the good stuff!
my favorite by far is the newton's cradle. too bad i lost it when i lost my entire house of freebies cause z severs didn't keep track of anything after dec. 2013 and i moved my freebies to another house out of boredom. right up there with newton's cradle is the steaming teapots.
