“And if that ain’t the truth, I hope—I hope I get run over by a streetcar!” says the wolf to a sceptical jury of wolves (and one skunk) in “The Trial of Mr. Wolf.” And that’s what happens.
It’s a gag used a couple of times in cartoons but you’ve got to admire Friz Freleng’s pacing here. No sooner does the wolf say his line than the streetcar roars over him. It takes less than a second (24 frames).
Here’s one foot (16 frames) of action, all on ones.
Dick Bickenbach is the credited animator. I can’t tell you who was handling layouts for Friz at the time (1941).
