Tonight Show host Jay Leno has apologized to a Kentucky physician for joking that the guy looks like Adolph Hitler. During his regular bit where he spoofs newspaper ads, Leno pointed to a photo of Dr. Ricky Collins, wisecracking, "He's no longer the chancellor of Germany. He's now a doctor." After Mrs. Collins called NBC to complain, Leno phoned them personally to make nice, and even donated $500 to the doc's favorite charity.
