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

Caterpillar ( CAT): "I am sorry but I think the analysts are wrong. This one yields 4.8%; I want to pull the trigger and buy Caterpillar."

Almost Family ( AFAM): "We've got a big nurse shortage in this country and this is the way to play it. Great call."

Citigroup ( C): "I have some of the highest quality banks stocks in Bank of America ( BAC), Wells Fargo ( WFC), BB&T Corp ( BBT) and Goldman Sachs ( GS). Why would I want to go into Citigroup?"

*For all you home-gamers, a 'mon-back opportunity means Cramer would back up the figurative truck and load up on a stock.
