About the Ski Shop Salesman[]
The Salesman encounters Mork in the midst of the madness of the Christmas shopping run up, with the Ski Shop particularly manic, and Mork hiding out under a table.
When Mork tries to restore his safety by making a faking announcement of a sale on the non existent second floor, he clears the place out, apologizing to the Salesman when he arrives. Who tells him not to worry about it, they'll all come back when they discover there's no second floor. Asking the Salesman for help with his purchases, results in a less positive response however, when Mork tells him that he only has 12 bucks for presents for 4 people.
The salesman strongly suggests he buys gifts at McDonald.
