With sold-out global concert tours, ratings-shattering broadcast specials, a best-selling autobiography, a star on the Hollywood Walk of Fame, and a Guinness Book of World Records title set for good measure, ventriloquist Jeff Dunham is a comedy superstar and one of the world’s most inventive entertainers. Today, the man TIME calls “a dressed-down, more digestible version of Don Rickles with multiple personality disorder,” announces additional dates for his upcoming Jeff Dunham Seriously?! tour. The worldwide trek kicked off this month with stops across the U.K. and Europe and will be launching in the U.S. on June 10th in Lincoln, California. Recently added dates include stops in Akron, Ohio (July 12th), Redding, California (September 16th), Oakland, California (September 18th) and Fort Wayne, Indiana (September 22nd). Dunham’s summer tour will culminate with the taping of his next hour-long comedy special at the legendary Warner Theatre, in Washington D.C.
