Here we see the same gag in two Frank Tashlin films more than 10 years apart: first a wolf trying to eat a single pea as a complete meal in "I Got Plenty of Mutton," then Jerry Lewis doing the same thing with a bean in Artists and Models. Greg Ford mentions on his commentary for "Mutton" that Tashlin also wrote this gag, uncredited, into "Mickey and the Beanstalk," but I haven't seen that in a while.
By the way, is it me, or does "Mutton" have unusually little dialogue for an early '40s cartoon? (There's no dialogue at all for almost half the picture, and after that the dialogue is mostly limited to the ram's pre-Pepe Le Pew lover schtick.) Most of the Warners cartoons in the early '40s were quite talky by comparison, very different from all the dialoguless cartoons they'd do in the '50s. Bob Clampett in particular could never resist having a character talk during a gag -- remember Daffy doing the trapdoor gag in "The Great Piggy Bank Robbery" and telling us every step of the way what he's doing.
