Cramer concluded by calling McDonald's a consistent "A-" student that's not very exciting compared to Burger King, which is a "C+" student that's hitting the books to become a solid "B" student.

Lightning Round

Here's what Cramer had to say about caller's stocks during the "Lightning Round":

Sprint Nextel ( S): "I have liked the stock but it's just moved too much. Let's wait for a pullback."

Bed Bath & Beyond ( BBBY): "I need to see a total breakdown of this stock before I can tell you to get in."

Baytex Energy Trust ( BTE): "These are all ratcheting down their distributions. I'm going to say don't buy."

Parker Hannifin ( PH): "You can't buy this one until it yields 4%. There's no floor in the stock yet."

Molycorp ( MCP): "No, no. When the market is bad, stocks like that won't hold up."

Frontier Communications ( FTR): "I do not believe that dividend is sustainable. I want to say to hold off."

Kimberly-Clark ( KMB): "It has a good yield, and with oil and gas coming down this one is terrific. I'm not against this one right here."

Zynga ( ZNGA): "This may be a decent speculative play. The question is, can they make money. It seems wrong to sell it here though."

Another Food Fight

investors should also have a high-yielding consumer packaged foods company in their portfolio, said Cramer, as he kicked off his third match-up of the night, this one between ConAgra Foods ( CAG) and Kellogg ( K).

Cramer said that if he were back at his old hedge fund he'd start a paired trade going long ConAgra and short Kellogg. Why? Because in an environment where the prices of everything from ingredients to packaging and transportation are falling, ConAgra has the most to gain.

ConAgra currently has 25 brands that are number one or two in their category, said Cramer, everything from Slim Jim and Orville Redenbacher popcorn to Pam cooking spray. While ConAgra has a plan for growth, executives at Kellogg seem to be stepping on their own toes.
