From the 1950 Merry Melodies short "Hillbilly Hare".

One of my personal favorite climactic sequences from a Looney Tunes short. Bugs (at first in disguise) tricks the two hillbillies into a square dance, and then finagles command of the fiddle to begin calling out dance instructions of his own...

Good old cartoon violence.

Bugs had a knack for turning plot to his advantage way back when.

My favorite musical moment with Bugs, with Barber of Seville in second place
