Because Tim's found the cable that he was looking for. It's absolutely no good as a cable anymore. From the loose end that he's gotten his hands on, it looks as if it was chewed through, and it's missing the connector on this end.

Kon and Bart would say he was a nerd, but, in non-subjective time, neither one of them was even ten years old yet. They'd hate him for pointing that out.
