After Dinner Bloat

The Library of Congress Paper Print Collection includes an early American Mutoscope and Biograph comedy called A Champion Beer Drinker (1903). The library's records describe the film as follows: "The action begins with one waiter after another bringing our hero glasses of beer, which he drinks in rapid succession.

In Happy Hooligan Turns Burglar (1902), a maid attempts to reassemble a policeman blown to pieces by a burglar's bomb, but she makes a mess of the job and the policeman comes out with a foot for a hand and a hand for a foot.
