Given a cartoon image and a caption. Caption: Come on! Do you have any idea how long it took to get through the turnstiles? Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
The shepherd is trying very hard to get his sheep onto the subway, even going so far as to painstakingly get each sheep through the ticketing turnstiles at the station entrance. Now he's encountered another difficulty: the overcrowded subway car he can't fit on, and he's quite exacerbated at this point. It's funny, in part, because despite his drive to get the sheep on the subway, it's unclear why he has the sheep there in the first place.
