Jimmy Johnson didn't do all those ExtenZe commercials for nothing.

The Super Bowl-winning coach, who is now a Fox broadcaster, is estimated by one website to be worth around $40 million. While a good chuck of that money surely comes from his Fox salary, another portion of that fortune must be from Johnson's lucrative deal with the popular male enhancement pill.

And the 70-year-old is not letting all that dough go to waste. Johnson on Wednesday tweeted a photo of him standing next to what appears to be his new private jet:

Now, there's a chance that Johnson is just pulling all of our legs. But he's got the money to buy a plane, and he's never been shy about tweeting out photos of his extravagant purchases.
