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:

Monsanto: "Just stay long. I'm typically not an arbitrager but everything I listen to and my partner David Faber makes me think that there's something coming. You probably want to be in MON."

SecureWorks Corp: "I am so gun shy on cybersecurity, I'm just going to go back to Cyberark. We had Palo Alto on the show last night and I thought he told a great story. Does anybody really care? I do but I don't want to push the group hard."

Celator Pharmaceuticals: "Come on man, the gain has been made! Cha-ching, ka-ching, cha-ching. Let's move on."

GoPro: "Ambarella reported a good number tonight, and they're a drone company, people are going to give a little halo to GoPro. I think if you can get to $12 it is time to skeedaddle."

Dow Chemical Co: "A charitable trust name. I think the stock is actually 10 points undervalued. Right here, right now, I want to buy it."

Fitbit: "I'm snake bit from Fitbit. I liked Fitbit but it's like, I can't take the Fitbit pressure. There we are ... I just feel you have to be very careful in this."

Big Lots: "Big Lots had a good quarter, what can I say. It's time for those stores where you get the bargains. I think you have to wait for it to come in a little because it had a run. But Big Lots is back."

Nokia Corp: "Nokia is not back. Now it's just a river in Finland."
