It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on caller favorite stocks at rapid speed:

Chipotle: "Look, I want you to buy Chipotle. It's almost 18 months after we had that last incident [on] December 7, 2015 with the norovirus at Boston College, and therefore I think we're really around the corner. The stock did run up to $480. It's come back down, and I think it's time [to buy]."

Sierra Wireless: "Well, Sierra Wireless has kind of almost doubled. We're late, too late in this game. You've got to go find something else. That one's had too big a move."

Synergy Pharmaceuticals: "Well, gastrointestinal disorders. It's a speculative stock. I'm not going to be against it. It's $4. There's some opportunity there."

Blackstone Group: "I have liked Blackstone very much. I think it's absolutely terrific. If that IPO market were to open up, it would be even better. I want you to stick with it."

Comcast Corporation: "I work for Comcast, they're the parent company of this network. They have unbelievable cash flow. They've got absolutely terrific growth in that cash flow, so I am a buyer. My charitable trust owns it."

Disclosure: Comcast is the owner of NBCUniversal, the parent company of CNBC and CNBC.com.
