Germans Love David Hasselhoff: Despite being largely forgotten in North America, the show is still hugely popular in the U.K., thanks to perennial reruns on the BBC. In fact, it is even considered one of the top few classic sitcom imports there. Some attribute this to the British affection for the "loveable rogue" archetype, which Bilko fits to a tee.
Iconic Character, Forgotten Title: Far more people are familiar with the name "Sgt. Bilko" than Phil Silvers, and the show was in fact often renamed after the main character in reruns.
Jerk with a Heart of Gold: Every now and then Bilko acts to help his squadmates, without the goal of profit for himself. For example, the entire plot of The Empty Store is his Batman Gambit to retrieve money one of them lost to a couple of card sharks.
