All the cattle in the Masai village had cross eyes.
One day the government vet arrived to check the health of the herds, with him was a young European vet direct out of training.
After the health check the topic of the cross eyes came up.
"There is nothing we can do for your cattle" Said the government man.
This was a major blow to the wealth of the village & their disappointment was great!
Seeing this, the young European whispered something into the chief vets ear.
“Are you sure?”
“Yes!” replied the European.
“We’ll see!” Said the chief vet who asked for a long hollow tube & the most prized cow to be brought forward.

Presented with the cow & tube the chief vet inserted the thin end of the tube into the cow’s rectum, took a deep breath, placed the thick end of the tube in his mouth & gave an almighty puff down the tube!
Nothing!
He repeated the procedure......
Again Nothing! The cow’s eyes were still crossed.
“I thought you said it would work”
“Honest it’s the latest technique for cross eyed cattle!” Replied the youngster. “Let me try!”
He removed the tube from the cow’s rectum, turned it round & inserted the thick end, took a deep breath, placed the thin end into his mouth & blew!
Pop! The cow’s eyes were straight!
“Amazing!” Said the chief vet. “Why did you turn the tube round?”

“You don’t think I would put the same end in my mouth as you? Did you?”
