Lisa: Dad, I think he's an ivory dealer! His boots are ivory, his hat is ivory, and I'm pretty sure that check is ivory.
Homer: Lisa, a guy who's got lots of ivory is less likely to hurt Stampy than a guy whose ivory supplies are low.
Lisa: Mr. Blackheart, are you an ivory dealer?
Mr. Blackheart: Well, little girl, I've had lots of jobs in my day: whale hunter, seal clubber, President of the Fox Network. And, like most people, yeah I've dealt a little ivory.
Bart: Dad, you can't do this. Stampy is my friend.
Homer: Don't worry, son. I'll get you a new elephant.
Blackheart: I'll take that one too.
Homer: Done.
Blackheart: All right, I'll be back in the morning to pick up Stampy.
Homer: Here's the keys.
Blackheart: Elephants don't have keys.
Homer: Well, I'll just keep these then.
