As Mr. Ed raises his head after Wilber awakens him by popping a paper bag, you can see a man's hand holding Mr. Ed's leg in the lower left side of the frame.
Wilbur: Ed, do you know why you sleep so late? Well, it's because you have no purpose in life. Now, you would be a happier, healthier horse if you had some work to look forward to each day.
Ed: Okay, send me to medical school and make me a brain surgeon.
Wilbur: All right, Rip Van Winkle, sleep your life away.
Ed: Wilbur - I resent being called a lazy bum!
Wilbur: Look, Ed, I did not call you a bum!
Ed: That's okay, find me a job, I'll pay my way!
Wilbur: Now you're talking! I'll put an ad in the paper right away.
Ed: What are you going to say?
Wilbur: Horse for hire. Want short working hours and plenty of carrot breaks.
Ed: That's my boy!
Wilbur: (after waking Ed up, and Ed asks the time) It's 10 o'clock, and do you have to sleep so late every morning?
Ed: Yeah - I've got tired blood.
Wilbur: I don't know why - it never moves.
Addison: (on his unemployed brother-in-law Ralph) Oh, I wish he could get a job - so I can get him off my back!
Wilbur: He's a press agent, isn't he?
Addison: So he claims, but so far the only thing he's pressing is me.
Wilbur: How long has he been out of work?
Addison: He's been collecting unemployment insurance so long, they've named a branch office after him.
