While filming the scene where the bazooka of soot backfires in Moe Howard's face, the special effects man put too much pressure on it and when it backfired, Moe got some large chunks of soot lodged underneath his eyelids, and it took several hours to clean them out. Moe suffered a similar injury in 1939's "Oily to Bed, Oily to Rise" when he got what resembled oil shot under his eyelids.
