First on-screen appearance of Bruno's father, Ambrose, the original "one armed bandit"! Scoundrel in his own right, and parental bane of Bruno's existence! No matter how good (or bad) Bruno gets, can he ever live up to the legend of Ambrose?
To me this strip is also significant for the creative lettering in the last panel. Ian often inserts special effects into his dialogue lettering like this. Artistically, it's one of the things that really distinguishes this strip to my eye, giving it a visual punch like no other. It also makes me completely envious, because Ian makes hand lettering look so darn easy, and I suck at it so horribly.
