'Jersey Shore' star the Situation may have a way with the ladies, but Jesse Eisenberg seems immune to his dubious charms.

On 'The Tonight Show' yesterday, host Jay Leno noted the reality star's success with the ladies during the taping of the show's fourth season in Italy (Sitch notoriously wooed a pair of blonde twins while overseas, a feat he calls "twinning").

At Leno's urging, the Situation demonstrated his pickup moves on Eisenberg, imagining that '30 Minutes or Less' actor was "an attractive Italian woman."

"I would have to say, 'Ciao, signorina.' That means, 'Hello miss,' in Italian," said the Situation.

But Eisenberg wasn't taking the bait: "I don't think I would respond to that."
