Gene Shalit, a movie critic and arts reporter for the “Today” show over four decades who was known for his puffy hair, oversized handlebar mustache and affection for groan-inducing puns, has died. He was 100. Shalit’s family announced the death Friday to NBC News, saying in a statement that he “passed away peacefully today after 100 years of an amazing life.” Shalit joined “Today” as a contributor in 1970 and became arts editor in 1973, later settling in for his segment, “Critic’s Corner.” When
