Actress, author, and comedian Rachel Dratch (far right) was at her alma mater (Lexington High) on Sunday to talk about her memoir, “Girl Walks Into a Bar . . . : Comedy Calamities, Dating Disasters, and a Midlife Miracle.” She was joined during the event by her mom, Elaine. The do-gooding Dratch is one of the many celebs who’ve signed on to join Paul Rudd next month in a New York bowling event that will raise money for Our Time, an organization that helps kids who stutter.
