Danica Patrick Shows Jay Leno Her Nice, Firm ... Grip

Danica Patrick has some pretty impressive hands.

Patrick dropped by 'The Tonight Show with Jay Leno' this week and discussed - among other things - Danica's legendary firm handshake. Naturally, Leno decided to bust out a grip tester for an official reading.

A woman age 30 to 34 has an average grip strength of 70 pounds, so Danica is definitely off the charts.

If you ever get the chance to meet Patrick - for your own safety -  we'd advise against a handshake or high-five.
