Off to the Opera (1952)

Those rabble-rousing magpies Heckle and Jeckle are watching high-society crowds going into the theater to see a performance of "The Barber of Seville" and decide to get some culture of their own by sneaking into the show. The stage-door manager tosses them out on their first attempt, but they finally get past him, leading to a wild chase as the opera is underway.

Off to the Opera has a runtime of 7 minutes.
