CSI’s CAT IN THE PORKPIE HAT

Waiting to board a plane in Chicago, “CSI” star William L. Petersen eyed a guy sporting a fly porkpie hat — and told him he’d buy it right off his head! “Okay . . . 400 bucks,” joked the guy. Instantly, Petersen whipped out his wallet and forked over four C-note$$!

“Wow!” said Mr. Porkpie – who snatched off the hat, slapped it on the star’s head and split before he could change his mind!
