Awful Orphan is a 1949 Warner Bros. Merrie Melodies cartoon, directed by Chuck Jones and written by Michael Maltese.
Pretending to be pinning a paper pattern for the coat onto Charlie, Porky succeeds in wrapping the dog up for mailing, and sticks a label on him reading, "To Siberia".
In spite of being stuffed into a mailbox, Charlie returns wearing traditional clothing and, while doing the Cossack dance, kicks Porky in the rear end until he ejects him into the hall.
As Charlie starts to leave, Porky approaches him, laughing maniacally and with an evil look in his eyes showing that he has finally snapped.
The screen fades to black, then the cartoon returns with a scene similar to an earlier one, but with the roles of dog and master reversed.
Awful Orphan was released on DVD in 2003 on disc 3 of Looney Tunes Golden Collection: Volume 1.
