Some examples of reworked jokes in Roscoe Arbuckle's films.
Some of these are reworked from earlier films, and some jokes were used in more than two films, for example the burning bed is used in Mother's Boy 1913, Fatty's Plucky Pup 1915 and The Rough House 1917.
The gag of bubbles blown through a hose in water to simulate drowning is reworked in A Noise From the Deep 1913, Bubbles of Trouble 1916 and Good Night Nurse 1918.
A stolen tux appears in Fatty's Magic Pants 1914 and is reworked from The Tragedy of a Dress Suit 1912, and is again used in The Waiter's Ball 1916.
Arbuckle appears as a cook in The Waiter's Ball 1916, The Cook 1918 and Hey Pop 1932. Many of the kitchen gags are very similar in these films (oh, and many jokes are reworked in his sound shorts).
