Cramer's lightning round: Bed Bath & Beyond is a buy

• 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.

Appian: "I think we may have hit the top. You know this thing's too hot for us. ... Let's take a little off the table with Appian."

Sportsmans Warehouse: "I prefer Dick's. ... If you've been to Sportman's and you like it, then that's definitely worth buying. I think Dick's is coming down, it might be a more attractive issue, though. ... Camping World is OK."

At Home Group: "I like it. This stock is 7-times earnings."

Parsely Energy: The only two oils I'm recommending are Pioneer and Chevron. And Pioneer, by implication [of merging with Parsely], I'm recommending Parsley."

Bed Bath & Beyond: "Yes, it is a buy. ... Buy BBBY."

Yum Brands: "Under $100, yes" it's a buy.

Amarin: "I think it's hype. ... At $5 it's worth a throw."

Vaxart: "That one's too speculative for me."

XPeng: "No. ... I am willing to do JD. I do like Alibaba."
