Cramer's lightning round: I like Blade Air Mobility over Joby Aviation

• 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.

Celularity: "Celularity is interesting. Nobody likes it, but this is the kind of company if you buy it here, you might just get real lucky. I say take a shot."

Joby Aviation: "We looked at that. ... But what really matters is I like Blade. We found out Blade is really cheap and growing in a lot of different places. I think that's the one you should look at and I'm not a big SPAC fan."

LHC Group: "No. I'm very selective when it comes to that particular group. I like UnitedHealth and I really like Centene, and the reason why I like those is because you don't get that kind of action when you buy one of those companies."

Pitney Bowes: "Return to sender. ... I don't like it."
