For many of Azaria's characters, much of their humor is derived from a "funny voice", such as "The Birdcage" and "Night at the Museum: Battle of the Smithsonian". He stated that "being funny with a funny voice is more my comfort zone, a broader character that I try to humanize, a kind of silly or wacky persona that I try to fill in," although he finds it "much easier to be someone much closer to myself," as it requires "less energy ... than playing characters that are so out there and high strung."
