How about this one I’ve just found:
Three turtles, Joe, Steve, and Poncho, decide to go on a picnic. Joe packs the picnic basket with cookies, bottled sodas, and sandwiches. The trouble is, the picnic site is 10 miles away, so the turtles take 10 whole days to get there.
By the time they do arrive, everyone’s whipped and hungry. Joe takes the stuff out of the basket, one by one. He takes out the sodas and realizes that they forgot to bring a bottle opener. Joe & Steve beg Poncho to turn back home and retrieve it, but Poncho flatly refuses, knowing that they’ll eat everything by the time he gets back.
Somehow, after about two hours, the turtles manage to convince Poncho to go, swearing on their great-grand turtles’ graves that they won’t touch the food. So, Poncho sets off down the road, slow and steady.
Twenty days pass, but no Poncho. Joe and Steve are hungry and puzzled, but a promise is a promise. Another day passes, and still no Poncho, but a promise is a promise. After three more days pass without Poncho in sight, Steve starts getting restless. “I NEED FOOD!” he says with a hint of dementia in his voice.
“NO!” Joe retorts. “We promised.”
Five more days pass. Joe realizes that Poncho probably skipped out to the Burger King down the road, so the two turtles weakly lift the lid, get a sandwich, and open their mouths to eat. But then, right at that instant, Poncho pops out behind a rock.
“Just for that, I’m not going.”
Or this one:
Little Nancy was in the garden filling in a hole when her neighbor peered over the fence. Interested in what the little girl was up to, he politely asked, “What are you up to there, Nancy?”
“My goldfish died,” replied Nancy tearfully, without looking up, “and I’ve just buried him.”
The neighbor was concerned, “That’s an awfully big hole for a goldfish, isn’t it?”
Nancy patted down the last heap of earth and then replied, “That’s because he’s inside your stupid cat.”
Only two more to go:
Two guys were walking their dogs and came across a bar. Since they were hot and tired from walking the dogs they decided to go in and have a drink. Unfortunately, the bar didn’t allow dogs. There was no place to safely secure the dogs, so they started thinking of ideas to get in the bar. Then one of the guys had an idea.
“Just watch me and follow my lead,” he said.
He walked into the bar with his dog and the bartender stopped and said to him, “I’m sorry but I can’t let you in here.”
The guy looked at the bartender and asked, “Why not?”
The bartender replied, “Well, we don’t allow dogs into the bar.”
“But this is my seeing eye dog,” the guy said.
“Oh, I’m sorry sir come on in, and by the way, nice golden retriever.”
The guy went into the bar and the second guy walked in with his dog. The bartender stopped him and told him he can’t let him in. When asked why not the bartender replied that you cannot have dogs in his bar.
“But this is my seeing eye dog,” said the second guy.
The bartender looked at the man and then looked at the dog. After a while he said, “Sir, ah… um… a Chihuahua?”
The man looked a little puzzled and then said, “What? They gave me a Chihuahua?”
And the last one, I promise:
“Some plants,” said the teacher, "have the prefix “dog. For instance, there is the dogrose, the dogwood, the dogviolet. Now name another plant prefixed by ‘dog’.”
“I can,” shouted a little redhead from the back row, “Collieflower!”
