One day, a man walked into a bar and sat down next to a horse that was sitting at the end of the bar. The man ordered a beer and started chatting with the bartender.
After a while, the man turned to the horse and asked, "Hey, why the long face?"
The horse replied, "Well, it all started when I was a young colt. I was a fast runner and I dreamed of being a racehorse. So, I trained hard and finally got my chance to race in the Kentucky Derby. But, as luck would have it, I tripped and fell at the starting line and was disqualified. I never lived it down and now I'm stuck here at this bar, drowning my sorrows in beer."
The man was taken aback by the horse's story and felt sorry for him. So, he decided to cheer him up by telling a joke.
"Hey horse, I heard a great joke the other day. Why did the scarecrow win an award?"
The horse perked up and asked, "Why?"
The man replied, "Because he was outstanding in his field!"
The horse laughed so hard that he nearly fell off his barstool. The bartender couldn't believe what he was seeing and asked the man, "How did you make him laugh like that?"
The man chuckled and said, "Well, I guess you could say I really know how to horse around!"
And with that, the man and the horse became fast friends, sharing jokes and laughs at the bar every day. And from that day on, they were known as the dynamic duo of comedy at the local watering hole.
