Glutony

A couple of hours ago I was craving for a snack.  I could've either gone to the nearest convenience store to get some potato chips or fry some french fries I have in the freezer.  Somehow I was too lazy for either, plus I know I shouldn't be snacking so much if I really want to lose weight.  Now I'm not really much hungrier than before, but much happier I didn't indulge.  How many calories must there be in a dishful of french fires with mayo?
