These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ear Worm: Ask any fan who remembers the show, and they'll probably tell you that the most memorable part was the theme tune, "Maybe Tomorrow". (Unless they're of a certain age in which case they remember the infamous parachuting dog image from the 1960s series which played over it's distinctive theme song.)
Leave The Plot Threads Hanging: Where did the dog come from? Where was he going? Who was his original owner? Why was he on the road anyway? None of these questions are answered during either series.
Narm Charm: The ridiculous situations the Hobo gets himself into, the hammy acting by the special guest stars and the low-budget cinematography (the 1980s series was videotaped) should have killed the show, but it still has immense nostalgic value to Canadians.
