Cramer's lightning round: Madison Square Garden Sports is a 'good idea'

• 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.

NantKwest: "I'm going to say yes, but it's a spec, and I'm fine with it."

First Solar: "If I really do want solar ... I want [Tesla CEO] Elon Musk."

Fair Isaac Corp: "I think you're fine with Fair Isaac. I'm surprised the stock is going down so much because it's fintech, but fintech is rolling over."

Madison Square Garden Sports Corp.: "I think it's a good idea."

PLBY Group: "I've got to do some work on PLBY."

Rocket Companies: "I think rates are going up, and so therefore that makes me a little bit biased against, but I listened to [CEO] Jay [Farner] — they've done well when rates have gone up, they've done well when rates have gone down. It's an inexpensive stock and they had a really great quarter."
