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

"Airgas(ARG Quote) is a company that actually sells gas, which turns out to be an unbelievable business. ... Airgas is a winner here." Cramer then played the sound of a truck* backing up.

Sonic Solutions(SNIC Quote): No ... no ... no. If you're gonna do digital video, you know we're going to do DivX(DIVX Quote). ... Cramer also said he was going to "gravitate, migrate" to Akamai(AKAM Quote), which reported a good quarter and also means smart in Hawaiian.

Vertex(VRTX Quote): "They actually own the hepatitis C franchise. I have to believe someone takes [acquires] them out eventually. ... BuyBuyBuy."

HealthExtras(HLEX Quote): "Another network pharmacy cost-saving play. I like Express Scripts(ESRX Quote), but I can get behind HealthExtras easily." Cramer owns Express Scripts for his Action Alerts PLUS charitable trust.

Terra Nitrogen(TNH Quote): "How bout Mosaic(MOS Quote)? which is the one we chose. Don't forget Quimica(SQM Quote), 52-week high. ... Terra Nitrogen fits right in with the fantastic dividend."

M & F Worldwide(MFW Quote): "This is a company that is run by Ron Perelman. ... I think Perelman's got the mo-jo on this one. I like M & F Worldwide."

American Ecology(ECOL Quote): "Three percent yield, kinda stalled here. I like the waste business, toxic waste. Not backing away."
