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

Transocean (RIG Quote - Cramer on RIG - Stock Picks): "You know I've liked RIG, it had a big run, so be careful there. I also like National Oilwell Varco (NOV Quote - Cramer on NOV - Stock Picks), they have a monopoly and they're my favorite."

Harley Davidson (HOG Quote - Cramer on HOG - Stock Picks): "I think Harley has been hit and hit from the weak consumer. I think this is the floor for the stock and I'm almost ready to pull the trigger on that one."

Hologic (HOLX Quote - Cramer on HOLX - Stock Picks): "I think they're getting their arms around what's wrong. I am in the 'don't buy' camp for right now. It's too dicey."

Verasun Energy (VSE Quote - Cramer on VSE - Stock Picks): "Oh man, I hate to be this negative. I don't want you sticking with that one."

UMB Financial (UMBF Quote - Cramer on UMBF - Stock Picks): "This thing sells at twice book and is one of the few regional banks that might be as good as Hudson City Bancorp (HCBK Quote - Cramer on HCBK - Stock Picks). I'm going to take a closer look at it."
