Is that a monkey in your pocket, or are you just happy to see me?

Guy gets busted at customs in Mexico City while trying to smuggle 18 endangered titi (yes, that's an actual species) monkeys into the country -- under his shirt. He was given away by a mysterious bulge in his jacket.
When he goes to prison, he better not drop the soap. He might get aped.
