EDIT: The company contacted me and requested that I take this offer down.
3M officially wears the crown for giving out the oddest freebies. To me 3M = paper supplies, so I was a bit perplexed to see them giving away free ear plugs in the shape of pistons.
They even gave away free dog food a few months ago! Was it made from old post-it notes? I half expected it to stick to the roof of my dog's mouth, kinda like peanut butter. It was quite a let down when she ate it normally and then went straight to napping on the couch.
