Clothing with some giant logo on it.
(Thank you Foot Shoppe for the free umbrella that says "Foot Shoppe" on it in huge letters. I will let you advertise on my umbrella as I walk down the street because you gave it to me for free. I would not pay anything for an item advertising someone's store or clothing line - such as sweatshirts that say "POLO" on them in huge letters. If RL gave those away for free, maybe I'd wear one, but I'm certainly not paying to be a human billboard).

Squirrels (my yard has plenty, thanks)
