Bugs Bunny finds himself aboard a riverboat bound for the South, not realizing for a minute he'd been shanghaied by accident, in "Mississippi Hare". Internet Archive has a Blue Ribbon reissue.
The character of Colonel Shuffle (an uncredited Billy Bletcher), it is said, was later rebooted as Yosemite Sam. Same size, attitude, everything. The hair simply changed from white to red.
Is it just me, or did Chuck Jones insist on Bugs being in drag for at least one scene in every film he directed?
