Lightning Round: Stay far away from this

It's that time again! The Lightning Round bell has rung, and Jim Cramer gives his take on a few favorite audience stocks:

Adobe Systems Inc: "No, that quarter was no good. Come on, we have to stay focused. That was not a good quarter. We are going to stay away from Adobe."

Box Inc: "I think Aaron Levie did okay. Honestly if I would have told that story, it would have had a much better narrative. They should have let me do that conference call and the stock would be at $22. I'm not kidding, he just didn't know how to tell the story. Once they got in the Q&A then they started weaving the story. This could be Palo Alto meets wrapped up into Red Hat. That's what they have to do. That is the way I would play it."

Rocket Fuel: "I don't know. Now the proof is in the pudding. The last two conference calls weren't that good. I think people feel like they don't need Rocket Fuel and just give the money to Google or their ad agencies. Let's see what happens there."

Tetraphase Pharmaceuticals: "I happen to like that space, and I like them because a lot of people feel that Merck overpaid when they decided to go into that space. I think that space is really important. I think antibiotics are something people are circling back to them, and anyone who has that from biopharma is going to be a winner here. That's my thinking, that the super bugs must be killed."

Berkshire Hathaway, Class B: "Both classes are terrific. I like Berkshire. I think Berkshire should be bought because you have to get deals like Heinz with him, and you can't yourself."
