Dream of Lifetime, or a Bad Idea?

We have a dear friend whose brother owns a bed and breakfast in Tlaquepaque, an "old town" section of Guadalajara. We always take visitors there because he has a beautiful atrium filled with tiny monkeys, marmosets, to be specific. They are not more than 8 inches tall, with sideburns that stick out... Some of them are in cages either because they are blind, or because they have a tendency to pee on people, but most of them are just loose, climbing in the trees, and going in and out of the rooms. They never run away, because monkeys are not stupid, and they know they will get fed every day if they stick around, with an occasional marshmallow as a treat.
Those of you who know me at all, know I have a passion for monkeys, and have always talked (half jokingly) about getting one. I know all the reasons why this is a bad idea: monkeys smell, some get aggressive as they hit puberty, they bite, and in the US they are illegal to own. And yes, I have seen the killer monkey episode of "Dirty Jobs". Here in Mexico, you are "not supposed" to own them. More of a suggestion, like a one-way street sign....
Anyways, last week we went to visit the monkeys with Walt's sister Margaret and her husband Dan. The monkeys have never come too close to us before, but this time they crawled all over me. The babies were sure that my bracelet was good to eat, and they wanted to crawl into my purse. So I asked the young man who had just fed them, if they would sell one or two. He thought maybe, but said I'd need to ask the owner.
Yes, I did smell like monkey all day, and yes, one of them did get a little enthusiastic in tasting my shoulder. Still, my question is, is this possibly the dream of a lifetime, or just a very bad idea? I already know what Eddie would say....
