You crack me up, GYO ... that was just TOO funny ...
Luckily for you, your're not relieving their boredom by taking them to the little petting zoo that was near my (then) home years ago .... at that little zoo, the "king" monkey among the d 15 or so who were in the rather large monkey cage would sit near the bars at the front of the cage and mooch smokes from visitors who were smoking as they passed his cage ...
He'd 'shout' and make a "gimme" gesture with his hands until he got a smoke ... he prefered cigars but would also take cigarettes, although he'd pull any filters off and toss those back to the the donors ... he liked all the smokes better if they were lit, but wouldn't reject any that were not ... he'd inspect 'em briefly to see if they were lit and if not, he'd just shove it in his mouth and eat it ... but, he'd puff a while on the lit ones and would then always eat the flame first before shoving the whole thing in his mouth ...
