Tom and Mark were the main characters of the show. Most episodes featured the two in interactive songs and sketches with kid-campers and in how-tos and comedy bits. Tom and Mark had alter-egos, "The Keeners", a couple of ageless campers so intent on coming back to camp each year that Tom and Mark gave them their moniker. In reality, the clips were in fast motion so that their voices would sound higher. The Keeners appeared in segments sharing camping tips taken to extremes and punctuated by one-liner jokes and groaners. Their popular theme song, ''I've Got a Head Like a Ping-Pong Ball
, became a cult hit and a generation of kids grew up reciting the Cariboo credo: "We'll follow the path where the cariboo walked, Our cariboo headgear is off, on, locked!"'' The coveted eyes-and-antlers ball caps worn by the Keeners were featured in an exhibit at the
Waterloo Region Museum. Another regular character was Uncle Wes (played by Tom) in a segment called "Woodsy Wisdom". Wes would usually make appearances around the camp fire telling old stories and offering camping advice. == Reception ==
