Cramer's lightning round: Buy AT&T right here, right now

• It's that time again! "Mad Money" host Jim Cramer rings the lightning round bell, which means he's giving his answers to callers' stock questions at rapid speed.

DocuSign: "Because it is the ultimate utility and I think that what happens, I'm not kidding, people use it and they love it and Adobe should've bought them. And I've got to tell you had Adobe bought them, I think the stock'd be flying. Adobe [is] actually coming down."

Western Digital: "Why buy Western Digital when you can buy Micron, which I think has more game?"

Clearway Energy: "I like renewable energy. I think it's a good company."

Revolve: "I like revolve, I like Etsy, O.K.? And I think both of them are good. Etsy upgraded tonight."

AT&T: "Right now. You buy it right now. You've got Elliott [Management] in there, those guys are incredibly good. ... I think ATT is going to come and do what they want because they are so darn smart."
