Conan O’Brien’s Tonight Show launches June 1. In preparation, he’s making his way across the country, from New York to LA, visiting NBC affiliates. Yesterday afternoon, he popped in to NBC Channel 5’s Fort Worth studio to say hi — and to do battle with that so-called and alleged Irishman Brendan Higgins. Higgins says, “We debated who between us had the more powerful hair. And I showed him what we do around the station to relieve stress, including the ‘cage fights’ we have in the station’s storage area.” Look for Higgins’ interview with O’Brien to air on Channel 5 in the days leading up to the launch of the new Tonight Show.
