Here's what Jim Cramer had to say about some of the stocks during the Mad Money Lightning Round:

Cisco Systems (CSCO) : "I think they're doing a good job. I'd hold onto it." 

MasTec (MTZ) : "That is a wise idea."

Atmos Energy (ATO) : "This is one of my favorites and I'm long it."

Energy Transfer Partners (ETP) : "That is the worst in the group. Stay away."

Allergan (AGN) : "This stock can't catch a break. Nothing matters. Allergan is the anti-Bitcoin."

Gentex (GNTX) : "I'm OK on it. I'll endorse it."

First Data (FDC) : "They had a crummy quarter and I think the company is stalled."
