My Favorite Joke

A man walked into a bar with a penguin. "Do you know how to get to Lincoln Park Zoo?" he asked. After getting directions, the man and the penguin left the bar. The next day, the man walked into the bar with the penguin. "Do you know how to get to Wrigley Field?" he asked. "I thought you were taking that penguin to the zoo!" exclaimed the bartender. "We went to the zoo yesterday," the man replied. "Today we're going to the ball game."
