'HIMYM' Creators Dish on Britney's Performance

"How I Met Your Mother"'s creators talk about her performance on the show. BRITNEY SPEARS made her big TV comeback last night as a lovestruck receptionist on "How I Met Your Mother" -- how did she do? Critics are praising Britney's turn as a secretary with a crush on the show's lead, JOSH RADNOR , as his character continues his quest for his future wife, and ET got the scoop straight from the show's creators and executive producers, CRAIG THOMAS and CARTER BAYS , on working with the pop princess. Thomas told ET that Britney helped carry the show to record ratings: "I guess the final numbers aren't in but I think it was like 10.6 million [viewers who tuned in] and we got a 4.5 in [the] 18 to 49 [demographic] which is a record -- head and shoulders a record for our series in three years -- so we're pretty excited about it."
