Here's what Jim Cramer had to say about some of the stocks offered up by callers on the "Mad Money Lightning Round" Wednesday evening:

Merck(MRK Quote): "We've got a bunch of lawsuits upcoming. I think the stock's gonna get hammered back to its 52-week low. ... Why not buy Schering-Plough(SGP Quote)?

Parker Drilling(PKD Quote): "You should sell it. It is always the laggard."

Toll Brothers(TOL Quote): "I think the next move for Toll is back to the low, low $40s."

Sepracor(SEPR Quote): "Beginning to get nervous ... too one-product sensitive."

Accenture(ACN Quote): "Ixnay on the Accenture."

Pulte(PHM Quote): "Tomorrow when all the bears come out of their den and start talking about Hovnanian(HOV Quote), Pulte will go lower. Only Centex(CTX Quote) makes a lot of sense to me here."

PetMed Express(PETS Quote): "This pet market has been not so hot. ... I am not a fan. If you need to be in the pet business somehow, go buy a dog."

Energy Conversion Devices(ENER Quote): "At 60 bucks [a barrel for oil], Energy Conversion is a winner."

Principal Financial(PFG Quote): "52-week high but I am not backing away."

BE Aerospace(BEAV Quote): "Insiders sell for many reasons. This stock is tremendously in bull market mode. ... 'mon back* anytime this thing gets to 13."

Salesforce.com(CRM Quote): "See a lot of competition coming to CRM. ... He's not for me that CEO."

Usana Health(USNA Quote): "I don't like the supplement business, and I think you should sell this."
