Roger's Disguise:

Saudi Princess from ‘Stan of Arabia: Part 2’

The title of this episode is a reference to the “Jif Peanut Butter” commercials of the 80's and 90's.
The 80's slogan was “Choosy mothers choose Jif” & it was changed slightly in the 90's to “Choosy moms choose Jif”.
It was updated again in the 00's to “Choosy moms & dads choose Jif”

Francine: “Oooh, Men's Warehouse?”
Stan: “I guarantee it”

Allusion to the clothing retail chain Men's Warehouse and its slogan the founder says in his commercials, “You're going to like the way you look, I'll guarantee it”

Stan: “If Ritchie Valens' plane had been just a little big smaller, he'd still be alive today”

Ritchie Valens (1941-1959) was an aspiring musician who died in a small plane crash in 1959.
He may be best known for his 1959 song “La Bamba”

Roger: “It's normal. You're curious, like the monkey except he was curious about whether the man in the yellow hat would violate him with a banana which is something to be curious about.”

Roger is referring to the title character of the book series written by Hans Augusto Rey & Margret Rey, “Curious George”.
“The Man w/ the Yellow Hat” is the character that brought George back to the city from Africa.

The famous cellist Yo Yo Ma (1955-) is mentioned in this episode.

Travis: “In fact, I'm on my way right now to birth a calf w/ John Cougar Mellencamp”

American musician John Mellencamp (1951-) is mentioned in this episode.

Mellencamp is probably best known for his work in the 1980's like “Little Pink Houses”, “Authority Song” & “Crumblin' Down”.

The 2 time Grammy winning American R&B/Soul singer, Peabo Bryson (1951-) is mentioned in this episode.

Roger: “Thirteen! That should do it! All right Seagulls. Take me home. Hyah!”

The way Roger has wrangled the seagulls is the same way the character “James” did in the 1996 live action/stop motion animated movie “James and the Giant Peach”.
It was based off the 1961 novel of the same name by Ronald Dahl

Roger: My sunglasses, where are my sunglasses? (Roger puts them on and screams when he realizes the lens is missing.)

This might be an allusion to The Twilight Zone episode featuring Burgess Meredith when he was the last person on Earth.
His character had time to read all the books he wanted but broke the lens of his prescription glasses.
