Hank Azaria, known for his voice work on The Simpsons, attempted to make a King's Guard at the Tower of London laugh by impersonating characters from the show, including Moe Szyslak and Chief Wiggum, but the guard remained stoic. Despite Azaria's efforts, the guard did not react, leading Azaria to humorously declare him the 'best guard ever'. This light-hearted encounter contrasted with the usual interactions tourists have with the guards, who are famous for their serious demeanor. Azaria's video showcasing his impressions garnered attention on social media, highlighting his talent for seamlessly switching between voices and entertaining fans.
