in 2012, during a PBS telethon, Jerry Stiller and Anne Meara spoke to the camera, side by side, just like in the Camp Hope promotional video. And the same music that played in the Camp Hope promotional video played in the background.
The story that Tony tells the boys during the hike is actually a confused mix of the myths of Icarus and Sisyphus. Sisyphus was a Greek king who tricked the gods on several occasions. As punishment, upon his death, he was forced to push a boulder up a hill for all of eternity. Before he could reach the top of the hill, the boulder would roll back down and he would have to start over. Icarus was a young man who tried to escape an island prison with his father, Daedalus, by making wings out of feathers and wax. Despite his father's warnings, Icarus flew too close to the sun, his wings melted and he fell to his death.
