Kevin James first appeared in season 1 in the episode, "Captain Nemo," as Kevin who is on Ray's recreational basketball team. James returned to the role of Ray's buddy in several episodes of the series' second season before starring in the show's spinoff sitcom, King of Queens, as Doug Heffernan.

In season 4, episode 17, "Hackidu," Ray's daughter, Ally, trades all of her Hackidu cards for a single card which Ray thinks is a rip-off and makes the kids trade back. When Ray realizes that the card Ally traded for was very rare and expensive, he tries to make things right by buying the card from Amy's eccentric brother, Russell who is played by Paul Reubens.

Reubens, who is best known for his signature role as Pee-wee Herman, originally played Amy MacDougall's brother before the character was portrayed by Schitt's Creek star, Chris Elliott as Peter. The show never addresses what happened to Amy's brother, Russell, but surprisingly, Elliott manages to bring an even more quirky and obnoxious character to the show than Reubens' original version of the character.

4 Terry Bradshaw

Ray has an interview lined up with former football star, Terry Bradshaw, about ghostwriting his biography but when Debra and the kids get sick, Ray has to take the kids to the doctor.

In the show's first season, episode, "Debra's Sick," Bradshaw enters the doctor's office completely dumbfounded until he sees Ray with his kids. The episode kicks off with comedy gold as Ray tries to hold a meeting with Bradshaw who casually takes a seat on a large stuffed giraffe. The football star's appearance isn't very long but manages to get some of the biggest laughs in that short span of time.

3 Barry Bonds

At the beginning of the episode, "Diamonds," Ray has just finished interviewing baseball icon, Barry Bonds, who is irritated by reporters always giving him a hard time about his salary. The two engage in an interesting conversation about their salaries and somehow, Bonds makes Ray feel like he's a millionaire too.

Ray's profession in the series sets up a number of appearances by professional athletes but Bonds schooling Ray about his 7 million dollar salary sets him apart from other guests. While the episode's title is a reference to Debra's wedding ring, the title is also a nod to Bonds and the baseball diamond field.

2 Kareem Abdul-Jabbar

In season 1, episode, "Frank the Writer," Ray's dad, Frank, writes a funny story that ends up getting published in Reader's Digest. The accomplishment makes Frank think he's actually a good writer and aspires to have a column just like Ray. Before Frank's big news, Ray has an unexpected guest over to the house, former NBA star, Kareem-Abdul Jabbar.

Jabbar's guest appearance has literally nothing to do with the rest of the episode but starts things off on a hilarious note when Debra doesn't even realize Jabbar is in her house. The fact that anyone would be asleep while in the presence of greatness like Jabbar is hilarious in itself and makes the basketball star one of the show's best celebrity cameos.

1 Jean Stapleton

When Ray's Uncle Gus passes away, Ray is asked to give the family eulogy for his favorite uncle. As the family gathers for the service, Ray is nervous about speaking, but he ends up with a bigger problem when his Aunt Alda arrives and tensions flare up between her and Ray's mother, Marie.

Stapleton is universally recognized for her role as one of television's most beloved mother and wife, Edith Bunker from the iconic family sitcom, All in the Family. Her hilarious appearance as Ray's aunt is not only the highlight of the season one episode, "I Wish I Were Gus," but also a fitting tribute to the American sitcom.
