Had to look it up. The full quote is great, even mentions his uncle at MIT.

Now they'll say all these stories are terrible. Well, these stories have, you know, you heard my story in the boat with the shark, right? I got killed on that. They thought I was rambling. I'm not rambling. We can't get the boat to float. The battery is so heavy. So then I start talking about asking questions. You know, I have an, I had an uncle who was a great professor at MIT for many years, long, I think the longest tenure ever. Very smart, had three different degrees and you know, so I have an aptitude for things. You know, there is such a thing as an aptitude. I said, well, what would happen if this boat is so heavy and started to sink and you're on the top of the boat. Do you get electrocuted or not? In other words, the boat is going down and you're on the top, will the electric currents flow through the water and wipe you out? And let's say there's a shark about 10 yards over there. Would I have to immediately abandon or could I ride the electric down and he said, sir, nobody's ever asked us that question. But sir, I don't know. I said, well, I want to know because I guarantee you one thing, I don't care what happens. I'm staying with the electric, I'm not getting over with it. So I tell that story. And the fake news they go, he told this crazy story with electric. It's actually not crazy. It's sort of a smart story, right? Sort of like, you know, it's like the snake, it's a smart when you, you figure what you're leaving in, right? You're bringing it in the, you know, the snake, right? The snake and the snake. I tell that and they do the same thing

Edit: I don’t even think this is the full quote, he wasn’t rambling though.
