One of my favorites growing up

A farmer had a very depressed horse. Very depressed indeed. All day and all night, all the horse did was mope and cry.

Aftertrying everything, the farmer finally gives up and puts an ad on the paper.

- ONE THOUSAND DOLLARS TO WHOM CAN CHEER UP MY HORSE.

Hundreds of locals showed up, each trying their best and failing, until the very last man. With all hope dwindling, the man whispers into the horses ear and suddenly...

-"Hahahahahahahahaha! BWAHAHAHAHA!"

The horse wouldn't stop laughing. "A miracle," says the farmer. "A true miracle."

Day and night the horse just laughs and laughs and laughs. Every day, every night, as loud as he could. The farmer finally got fed up. He couldn't sleep a wink for a week. So he posts another ad on the paper.

- TWO THOUSAND DOLLARS TO WHOM EVER CAN SHUT UP MY HORSE!

Hundreds show up and try their best, again, to no avail. Until the very same man, last again, asks the farmer for some privacy in the barn with the horse. A minute goes by and the horse exits. Mopping and sobbing, exhaling profusely, no longer laughing.

The farme is astonished. "How is this possible. Not just once, but twice this great man has accomolished that which none could. SIR! How did you do it? First you gave him the cheer of his life, now you have finally shut him up. How?"

-- "Well, first, I told him I had a bigger dick than him, which he found quite amusing. Then, I showed it to him."
