You gotta love this one, especially the drawings of Old Man fudd as seen on this model sheet.
This one, I think, may have been the first time a toddler version of an already cartoon character appears on-screen, which also was turned into a popular trend in the 1980's (i.e. Muppet Babies, Baby Looney Tunes, ect.)
Also, watch for hidden newspaper gags like during the "Smell-o-Vison Replaces Telovision" headline, it states, "Carl Stalling Sez, 'It'll never work!'"
It'll be more fun if you watch the film here:
Merrie Melodies - The Old Grey Hare (1944)
