Bag of Farts Candy is a small biz specializing in, well, the obvious.
Promising review: “I won’t lie, the whole reason I purchased this is because I knew that my kids would laugh at the name. However, I was really happy with how yummy the actual cotton candy in the bag was! The candy was fresh, and well packaged, and the product name got the laughs expected. Overall, I would say it’s a bit expensive for what you get (though it was easily enough for me and two children to share), but would still recommend as a cute/silly gift for someone who would get a kick out of this type of thing.” —Deb
