It turns out there's only one thing that capuchins really, really love - and that's sweet stuff. If you give them a big vat of say, marshmallow fluff, and you let them go at it, what they'll do is eat their body weight in marshmallow fluff, walk away, they'll vomit, and they'll come back and eat their body weight again. And they'll vomit. And they'll do that for as long as there is marshmallow fluff out there. They love marshmallow fluff.
