There were two men at a bar

There were two men at a bar, the first man said to the other one, “I know a bridge where you can jump off and return safely.”

The other man who was shocked asked the man to show it to him.

After they finished their drinks the second man asked him to demonstrate, so the first man jumped off the bridge and flew back.

The second man dumbfounded decided why not give it a try.

He jumped off and died.

When the first man went back to the bar the bartender said, “Superman you are so cruel when you are drunk!”
