Linda's Giant - S6.E32

Nobody gives Linda's imaginary friend, Mr. Jumbo, a second thought until a school psychologist visits Danny and Kathy and suggests that Linda cannot separate fantasy from reality and faults Danny for all of this. Danny does all he can to spend quality time with his daughter, but when pressed, Linda will not admit that Mr. Jumbo is a figment of her imagination. Danny threatens to spank her for lying to him, but she is literally saved by the bell, when "Mr Jumbo," a new doorman at an adjacent building is at the door.
