Given a cartoon image and a caption. Caption: You were with Ringling Brothers? I was with Lehman Brothers. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
A joke about the 2008 financial crisis: both the clown and the bartender were fired and worked for "Brothers" --- the Ringling Brothers (a circus company) for the clown, and "Lehman Brothers" (an investment bank) for the bartender. The similarity of the names and their intersecting sad stories makes the situation unusual and funny.
