Matthew who? There’s another McConaughey who is the big man in Texas.

Self-made multi-millionaires Rooster McConaughey, Matthew’s older brother, and Butch Gilliam, return for the second season of CNBC’s West Texas Investors Club, offering up advice to budding entrepreneurs who are hoping to win over the guys with their product pitches.

The catch? The deals are made on their turf, deep in the heart of the Lone Star State. ET got a special invite behind the scenes.

“We're looking for someone who reminds us of us,” Butch says of what they look for in a potential investment.

“When they leave here, the most important thing is to help them help themselves. It’s not about getting the investment,” Rooster adds.

The longtime partners and friends know a thing or two about making (and losing) money. Rooster made his first million when he was 30 years old working in the oil pipe business. “The first money that I made and lost in two days?” he recalls.

“It didn’t last long. I mean, I rang the bell and I was kicked out of the park,” he adds.

Rooster has come a long way since then. His net worth is estimated to be over $55 million--giving his Oscar-winning brother a run for his money!

“I always say I was a famous drunk before he quit crapping his pants,” Rooster says of his kid brother.

“When Matthew was getting really famous, that was a lot of fun. In the beginning, when it first started, it was probably the most exciting for us, you know, the fact that he got into that stuff,” he shares.

But even during the future Oscar winner’s early success, Rooster didn’t let that get to his head.

“I remember we went out there after the Dazed and Confused premiere and we stayed up all night long,” Rooster recalls. “About 11 o'clock that morning I got a call to his house, it’s a producer and it was Angels in the Outfield, and I said, ‘What's the deal?’ ‘Man we can't find Matthew.’ I said, ‘What?’ They said, ‘Well, we think he missed his plane.’ And I said, ‘Well, you need to fire his a**!’ I said, ‘Bygone, if he ain't gonna make it on time on the first day I'd fire that son of a b**ch!’”
