Bicycle of the Apes

What?

Nine blocks?

No helmets?

Wearing monkey masks?

Eight kids in horrible accidents and no one bothers to stop?

[Who knows what darkness lurks in the hearts of kids?] [1] [2]

Then again, it was the 60s, so maybe that explains this creepy bicycle safety film from 1963 (One Got Fat) [3] (via Robert Lee [4]).
