Bob Newhart stars as Bob McKay, a comic book artist whose super hero creation, Mad-Dog, makes an unexpected comeback.

Trisha smells a rat when she sees her boyfriend Matt with another woman eating a meatball sandwhich, but the real rodent may be Bob, when he incorporates her romantic problem into Mad-Dog's first storyline.

Bob's first issue of ""Mad-Dog"" comic books may get the boot from Ace Comic Books toughest critic: Smitty, the shoe shine man. Mr. Terhorst sets up a ""focus group"" to critque Mad-Dog.

Bob and Harlan and the rest of the crew go ballistic when they discover that Albie is responsible for the missing last page in the all-important first issue of Mad-Dog comics. Harlan fires Albie but later re-hires him when it turns out it was a good idea.

Bob's hopes for a happy Thanksgiving are deflated when his 70-foot-tall ""Mad-Dog"" balloon takes flight the night before the Macy's Thanksgiving Day Parade.

Bob's surprise birthday bash becomes a tale of torture when he develops a migraine headache just before two flamenco dancers unleash their 'hell' on his new hardwood floor.

Trisha is dumped by her boyfriend Matt, but she finds romance with the mysterious Mr. Terhorst, Bob's Boss.
