Cramer's 'Mad Money Recap': The Natural Gas Boom

Cramer said "there is still a lot of growth left for cable." He said Comcast is enjoying growth in high-speed Internet customers as well as in cable TV subscribers from the upcoming analog-to-digital switchover.

Cramer also said he mistakenly assumed Verizon's FiOS fiber service would kill cable. There, he said he failed to consider that FiOS is only available in 22.9% of Verizon's coverage area. Comcast is the better alternative where FiOS isn't available, he acknowledged.

Comcast also surprised Cramer with its ability to compete with the phone companies by using aggressive marketing and by adding more features to its lineup.

Cramer also mentioned his surprise at Comcast listening to activist investors and buying back some of its stock, implementing the company's first dividend and cutting the multimillion-dollar benefit package of founder Ralph Robertson to $1.

Finally, Cramer said he misjudged Comcast's ability to fix its customer service problems. "Competition forced the company to address their issues," he said, citing the company's reduced repair calls for the most recent quarter.

Cramer said he thinks Comcast looks good here and is worth buying.

Waste Management: Part II

Cramer again welcomed David Steiner, CEO of Waste Management (WMI Quote) to the show to discuss his company's outlook.

Steiner said that most of Waste Management's business is recession-proof and the company has a lot of leverage to bring to the market. While volumes had slowed down in previous quarters, they began to rebound in April and he expects the company to still meet its numbers for the year.
