Ho ho ho! It’s me Santa and my lil’ helper here! Wishing you all a merry Holidamas for a hundred years! (If you so happen to find Doc not celebrating, it’s cause I covered this year. Also he’s got a time car, can’t expect a guy to pay attention to everything.)
Santos L. Halper — The Canine Mutiny, April 13, 1997.
When Bart complains he never gets any mail, Marge gives him the family’s junk mail. One piece contains a credit card application, which Bart fills out under the name of his dog Santa’s Little Helper, whom he claims to have the occupation “butt doctor”. The company misreads the name as “Santos L. Halper”, and the credit card application is approved.
