>sometimes this goes hilariously wrong (like the internet being a series of tubes)

That didn't go hilariously wrong, though - the internet is a series of tubes. Not physically (copper cables aren't tubes) but he obviously wasn't talking about specific stuff but broad-strokes analogy (his exact line was "It's not a big truck. It's a series of tubes."), and his description was basically accurate.
