"Bad" foods that are addictive

Almost all of you who have joined MFP (with the small exception of a few creepers and possible stalkers), are here to improve your diet and to work on becoming more fit. However, no matter how much progress many of us make, there's always one snack or some kind of junk food that can easily set us back once we get our hands on it. For example, I could be cruising along fine and making all kinds of progress until I pass a place like "Wingstop" or "BW's" Hot wings will probably lead to my down fall. LOL. What are you addictions? Donuts? Cupcakes? Fried bacon?
