Family Guy: 10 Best Characters Who Only Appeared In One Episode

10. Big Fat Paulie (Season 2, Episode 16)

In the episode "There's Something About Paulie," Peter Griffin truly jumped into the deep when he needed to find a new family car. After a failed first attempt, Lois' dumb skull husband was pressured to find a more suitable vehicle and fast. Despite the endless funds he seemed to have for his never-ending hijinks, he found himself in a financial bind and stuck with a worthless car.

There were numerous ways Peter could have overcome his plight, but he chose the least reasonable option of enlisting the help of some mafia members, to whom he ended up owing a favor.

To repay his debt, the head of the Griffin household had to spend a night with Big Fat Paulie, an annoying greaseball no one else was able to handle... aside from Peter. When Lois got sick of her hubby's new friend, she demanded they spent less time together. Paulie took her comments personally and placed a hit on her, which he could not dismiss before his untimely demise.

While Big Fat Paulie only made one appearance in Family Guy, the unredacted hit placed on Lois would have made for a terrific multi-seasonal running gag, but it, too, went away. The only other time the mafia man was mentioned was during Stewie Griffin: The Untold Story when his grave was believed to be discovered.
