Given a cartoon image and a caption. Caption: Frank called to say he'll be late, he's stuck at the office. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
A play on the term "stuck in traffic" --- when people commute, they will sometimes miss meetings because they are stuck in traffic. But here, the meeting is taking place on transit, and the location the missing person is is flipped: in a funny twist, they are stuck at the office (where meetings would usually take place), and will miss the transit meeting.
