Four of his elves got sick, and the trainee elves did not produce the toys as fast as the regular ones, so Santa was beginning to feel the pressure of being behind schedule.
Then Mrs. Claus told Santa that her mother was coming to visit. This stressed Santa even more.
When he went to harness the reindeer, he found that three of them were about to give birth and two had jumped the fence and were out, heaven knows where. More Stress.
