"An Evil Petting Zoo?"

I always refer to this line. People seem to forget it. For some reason it stuck with me.

I mention it when someone thinks of something crafty.

Person: You don't have to buy it if you just need it for one night.

Me:

Person: You can just be careful when you take the tags off. You can put them back on and return it.

Me: EVIL petting zoo

Person: Wuh?
