One day, a man walks into a bar with a pig on a leash. The bartender looks at him and says, "Why do you have a pig in here? We don't allow animals."
The man replies, "Oh, this is a very special pig. He can do tricks!"
Intrigued, the bartender asks the man to show him. The man nods at the pig, and the pig promptly starts doing flips, cartwheels, and even balancing a beer on his snout.
The bartender is amazed and asks, "That's incredible! How did you train him to do that?"
The man smiles and says, "Well, it all started when I was stranded on a deserted island with nothing but this pig. We had to survive together, so I taught him all these tricks in order to keep us entertained and sane. And now, here we are!"
The bartender is impressed and offers to buy the man and his pig a drink. As they sit at the bar, the man looks at the pig and whispers, "Hey, remember that time we were stranded on that island and had to eat each other?"
The pig looks back at him with a grin and says, "Yeah, good times."
