Sir: Why did the chicken cross the road?
Andrew: One does not know, sir, possibly a predator was behind the chicken, or possibly there was a female chicken on the other of the road, if it's a male chicken. Possibly a food source, or depending on the season it might be migrating. One hopes there's no traffic.
Sir: To get to the other side.
Andrew: To get to the other side. Ah, why is that funny?
