A bad habit
I overheard a friend telling his pal, "I can't break my wife of the habit of staying up until 5 in the morning.""What is she doing?", the pal asks."Waiting for me to get home."

A walking economy
This guy is walking with his friend, who happens to be a psychologist. He says to this friend, "I'm a walking economy."

The friend asks, "How so?"

"My hair line is in recession, my stomach is a victim of inflation, and both of these together are putting me into a deep depression!"
