Tex Avery and his gagmen (generally Rich Hogan or Heck Allen) used routines over and over until even Tex got to the point of wondering if they were still funny.
One that surfaced a couple of times in Tex’s early days appeared in Dangerous Dan McFoo (1939). A trio is singing that vererable old melody “The Quilting Party” when it stops and mugs for the camera. Tex holds the pose for 46 frames before the characters resume singing. He pulled the same gag the previous year in The Penguin Parade.
The song concluded, for some reason Avery has the singers thrust their crotches at the camera (accompanied by a timpani) before scooting out of the cartoon in mid-air.
The story in this cartoon is by Hogan. Avery’s animators around this time included Virgil Ross, Sid Sutherland, Ham Hamilton and Paul J. Smith.
