Season 1

Ted decides to give Casey, his bride-to-be, a surprise wedding gift - a reunion with her long-lost father, Leo. Ted doesn't realize, however, that his bride cannot tolerate her father. Ted doesn't really understand this attitude because Leo is nothing like his own father, George, a quiet bookstore owner. Leo, a small-time hoodlum and part-time magician, can't go back to Las Vegas because he kept the last payoff he collected. Soon enough, a hit man arrives at George's home to collect the money. Leo's this close to getting whacked until George intervenes. The mob's on hold for now, but that's the least of George's problems because, on his way to the ferry, Leo happens to notice the spare room above George's bookstore. . . .

George is so desperate to get Ted and Casey married that he turns to Leo for help. Minutes before vows are to be exchanged, Casey's mother decides to tell her the real story behind her brief marriage to Leo, which so discourages Casey she goes running from the altar. George, who is even ready to accept a roller-blading priest to get the deed done, has to turn to Leo, a one-man fidelity wrecking crew, to set things straight.

Leo and George enrol in a baby care class in an attempt to ready themselves for grandfatherhood, but their first assignment leaves them sifting for ways to reverse their troubles when their ""baby"" — a flour sack — has an accident. Leo wants to prove to Casey that she can count on him to babysit, so he enrolls himself in a baby care class, dragging George along as well. The two men are by far the most unusual couple in the class, and their first assignment is to care for a 10 pound sack of flour as though it were their baby. Unfortunately, the ""baby"" accidentally rolls off the roof of Grandpa George's car, and he and Leo then concoct a scheme to get a new ""baby,"" hoping no one will know the difference.

In order to prove to Ted and Casey that he'll be a good grandfather and help out financially when their baby is born, Leo ""borrows"" some of George's things and takes them to a pawn shop.

And Ted and Casey, afraid for their sanity after spending too much time together, decide that Casey needs some R&R. But when she retreats to The Harbor Inn, her respite is disturbed by a group of pro wrestlers — and by some other unwelcome intruders. When several books mysteriously disappear and lights begin to turn themselves off and on, Leo is convinced that the ghost of Rumsey Reeve, the headless sailor, has come back to haunt the bookstore.
