(direct translation)
Bob: I have found an old method of transport.
Fred: Good job!
Bob: Papers found in the compartment opposite the driver's side (glove compartment) says that this method of transportation was called a car.
Fred: The humans probably called this mechanism a jalopy.
Bob: You are very wise on the subject of language.
Fred: It is likely that you could be too...if you stopped using slang.
