Slicker Puns

He can't afford to buy a whole herd of cows all at once, but he figures he can start small and work up. So he buys a dozen cows and two bulls. He puts the bulls in separate pastures, and splits the cows evenly, and waits. After a couple weeks, he realizes that most of the cows in one pasture are pregnant, but on the other side of the fence, nothing has been happening. He calls up his neighbor, Elmer, an old country feller who has been farming since he could walk. "See, there's your problem," the old man says, "That one's a bull, but the other's a steer." The city slicker says, "Well, I don't know what the difference is. Could you put it in terms I might understand better?" Elmer says, "Well..."

"One's regular and the other is de-calf."

You’re 40, she’s 10 – A classic  Abbott and Costello skit, where  Bud Abbott tries to play a prank on  Lou Costello, only for Lou to use his clownish math skills.

Slicker Smith (Bud Abbott): You’re 40 years old and you’re in love with this little girl that’s 10 years old. You’re four times as old as that girl and you couldn’t marry her, could you?
Herbie Brown (Lou Costello): Not unless I come from the mountains.
Slicker Smith (Bud Abbott): All right- you’re 40 years-old, you’re four times as old as this girl, and you can’t marry her, so you wait five years. By that time the little girl’s 15 and you’re 45. You’re only three times as old as that little girl. So you wait 15 years and when the girl is 30, you’re at 60. You’re only twice as old as that little girl.
📷****Herbie Brown (Lou Costello): She’s catching up.
Slicker Smith (Bud Abbott): Yes, yes. Now here’s the question. How long do you have to wait until you and that little girl are the same age?
Herbie Brown (Lou Costello): Now what kinda question is that? That’s ridiculous!
Slicker Smith (Bud Abbott): Ridiculous or not, answer the question.
Herbie Brown (Lou Costello): If I wait for that girl she’ll pass me up. She’ll wind up older than I am.
Slicker Smith (Bud Abbott): What are you talking about?
Herbie Brown (Lou Costello): She’ll have to wait for me!
Slicker Smith (Bud Abbott): Why should she wait for you?
Herbie Brown (Lou Costello): …I was nice enough to wait for her!

Original in Mandarin, so I may not have done the best job translating.

A country boy comes into the city for the first time in his life. He's never seen a skyscraper before, so he's standing on the street staring up in amazement. A city slicker walks by and says, "Excuse me sir, you realize there's a tax for counting stories don't you?"

"Oh, OK"

"How many stories did you count on this building?"

"10"

"That'll be 10 dollars please"

The country boy hands over the 10 dollars. The city guy takes the money and walks away, thinking to himself, "what a dumb hick, who'd believe such a thing as a counting-stories tax?"

The country boy walked away pretty pleased with himself, thinking, "what a dumb official, I actually counted 20 stories"
