Insulting mother-in-law

[Sonny]

When Santa came home, his wife, Jeeto, was crying. "Your mother insulted me," Jeeto sobbed. "My mother? How could she do that when she is on vacation on the other side of the country?" Santa asked. "I know. But this morning a letter addressed to you arrived. I opened it because I was curious." "And?" "At the end of the letter it said, 'Dear Jeeto, when you have finished reading this letter, don't forget to give it to my son.'"
