Doc! Hey, over here. Dr. John Dolittle:
What are you doin' here? Lucky:
You're unbelievable. I crossed three freeways at night no less, to come to rescue you, and all I get is, "what are you doing here?" Dr. John Dolittle:
This isn't a prison, it's a clinic. Lucky:
Look, the tigers in bad shape. Dr. John Dolittle:
The tiger? Hey listen. Forget the tiger. You know let me tell you somethin'. I had a perfect life until you came along and started talkin' to me. Now I'm sitting here in a robe and slippers discussin' Mister Ed with these guys. You ruined my life enough. I don't want to talk to you anymore. Go away. Just get out of here, please. Go, this is crazy. Lucky:
Oh, I get it. Now it's crazy to want to save a tiger's life. Dr. John Dolittle:
Listen, tigers die everyday, it's called nature. Lucky:
Let me tell you a little about nature. I'm a dog and I act like a dog. I don't try to be anybody else. We are who we are and you are a doctor who can talk to animals. That's who you are. Dr. John Dolittle:
That is not who I am. Lucky:
Stop lying to yourself. Dr. John Dolittle:
Didn't I tell you to get out of here? Get out of here! Go! Get out of here! Get out of here! Lucky:
[finally fed up]
Fine. Dr. John Dolittle:
Stop coming around here and talkin' to me! Lucky:
With pleasure. Dr. John Dolittle:
You better not come back! [Starts shouting] Lucky:
Bonehead. Dr. John Dolittle:
[to animals]
That's all of y'all! Leave me alone! Stop talkin' to me! Lucky:
[walking away]
Ruined his life. That's a laugh. Dr. John Dolittle:
