Help me understand this joke

There’s a friend of mine who thinks the red brick joke is the funniest thing she’s ever heard! She cracks up every time someone says “red brick”. She was the one who first told it to me- her hysteria in telling it was infectious and, by the time she got to the punchline, I thought it was hilarious, too. We were literally rolling around on the bed!

I know it’s meant not to make any sense, but that was really the funny part of it, that and my friend’s great delivery.

Are we thinking of the same joke? A red brick does make sense…if told in both parts. It’s kind of meta, but it does make sense.

Gotdammit, Shagnasty! You explained to soon. Don’t you know how this joke is played??

That is my favorite prank by the way. I hardly ever get a chance to do it.

No. He is reluctant to reveal the hippo’s gender because that would raise suspicion about what the zookeeper does with the hippo after hours. Because, y’know, anyone left alone with a hippo is going to have sex with it eventually…if it’s the right gender, that is. Unless they’re weird.

It’s my favorite prank too. For anyone interested the (what appears to be) original punchline has a wikipedia entry:

I also love general long pointless jokes. They work so much better with speech though. Purple socks is my favorite (it’s usually purple something, the original may hav b een purple gorilla from searching around on it, not sure). I may type it sometime.

And yeah I figure it’s anti-humor or, something lewd insinuating bestiality, but I try not to think about that last one.

What’s the joke?

I laughed. I don’t know if people are over analyzing this or I’m being whooshed, but I thought it was funny because you’d expect a zoo keeper to be very helpful and knowledgeable about the animals there, but yet he’s giving the woman lip like a stereotypical New Yorker. What makes it funnier is that her question is so formal and proper.

It’s sort of reminiscent of the old joke traditionally told by a guy: “How do you tell when a woman has an orgasm?”

Who cares?

The joke in the OP got an almost chuckle out of me. It has a existential air about it, what difference would it make to the woman what gender the hippo is?

There was a Peanuts strip that for years I didn’t get. Charlie Brown lends a book to Linus; a ghost story. “It’s really interesting,” CB says, “and yet it’s not too scary.” Linus reads it, then brings it back, saying, “You were right; it was only mildly frightening!”

Don’t know how many times I looked at that strip before I noticed the one hair standing up on Linus’s head.

Reminds me of the joke,

Q: How many feminists does it take to screw in a lightbulb?
A: *That’s not very damned funny! *

And now, it’s time for the penguin on top of your television to explode.

The first part of the joke is:

Three pigs are throwing bricks in the air. (Yeah, I’m not sure why, go with it.) The first pig throws a blue brick in the air and it goes up about ten feet. The second pig throws a green brick in the air and it goes up about twenty feet. The third pig throws a red brick up, and…it doesn’t come down.

So that goes over like a lead balloon and no one getes it. You’re then supposed to wait a while before you tell the next part.
The next part is:

There’s an airplane. A man is smoking a cigar and getting increasingly pissed at a crying baby in the next row. The baby’s mother asks the man to put out his cigar. When he refuses, she grabs the cigar and throws it out of the airplane. He responds by taking the baby and throwing it out. There’s silence–except for the sobbing of the mother.

When the airplane lands, to everyone’s shock, the baby is sitting on the wing of the airplane. And what do you, dear reader, suppose it had in its mouth?

The version I heard (late 60’s) was the same as yours except it was 2 elephants in a bathtub.

The penguins are psychotic, Marty…

Me, too. 1981.

What did he say?

I heard it with a lion and a lioness in the bathtub. I like that because it seems to suggest that the humor is gender- or sex-related.

We told it with elephants in the tub.

There was a TV show (short-lived) named No Soap, Radio. I liked it - it seemed very few others did. I guess they didn’t get it.

I figured out a secret punchline for the penguin/radio jokes in case anyone presses the issue.

Think how penguins and radios are similar.

They both travel in waves

Boy, people sure will feel dumb for not getting that zinger if you have to tell them.

This is quite possibly my favorite joke of all time. The way I heard it, it was an obsessive compulsive home builder in the first part fretting over having one brick left over, and the second part was a chihuahua and she pulled it back in the window by it’s leash. I also think the joke is a lot funnier when you really embellish it, taking several minutes to tell each part. I one time actually waited about a week before telling the second part… AWESOME. Of course, anyone who’s heard me tell it before always groans when I mention it, so it just make the audience that much more interested in hearing it.

As for the OP, I think the joke is supposed to be that the zookeeper interprets her question sexually, as in, he takes it accusatory that he’s having sex with the hippo because he is.

He said, “Property of the Zoo.”
