While teaching the alphabet to George in Curious George Learns the Alphabet, the Man in the Yellow Hat leaves George with an easel with some words using the letters George has learned up to this point written on it to study while the Man goes to fix George's lunch. The Man returns to find George having knocked the easel down and punched his head through the paper he was supposed to be studying◊.
Man in the Yellow Hat: George, I want to remind you, those ducks are here temporarily!
Narrator: George wondered exactly how long he could make "temporarily" last.
In "Zoo Night," George spends a good portion of the day entranced watching a video of a baby panda at the zoo on the Man in the Yellow Hat's computer. He finally gets him off of it by revealing that the zoo the panda's at is just down the street and so George can go see the panda in person.
He ends up staying past closing and letting several animals lose around the zoo. Then he puts them in the wrong places, like putting the giraffes in the bat habitat.
In "Curious George Meets Allie-Whoops," after Allie meets the Man in the Yellow Hat for the first time, she refers to him to George as "The Man in the Yellow Pants," possibly because he isn't wearing his hat when she first meets him.
In "Curious George Takes a Dive," George turns the bathtub into a miniature pond, complete with a turtle, fish, frogs and slime.
Man in the Yellow Hat: George, has it really been that long since I cleaned the tub, or did you do this?
In "Skunked," George and Bill both get sprayed by a skunk. Bill advises George, "take a bath in tomato juice." This is actually George's third time getting sprayed. He knows.
The episode's ending, where everyone in George and the Man in the Yellow Hat's apartment building are trapped in the elevator with the skunk. All of them attempt to keep quiet, George having a radio on with calming music to relax the skunk. However, everything goes sideways when the radio program changes...to what is said to be the loudest song of all time.
Radio Announcer: (Through Radio) That ends are program of Melo-jazz. And now, highlights from the 1812 Overture!
(The music BLASTS through the speakers and everyone screams as they are all skunk-sprayed.)
In "Cat Mother," George babysits a kitten and it gets stuck within the wall of his and the Man in the Yellow Hat's apartment. The building manager is forced to take a hole out of the wall to get the kitten out. When the Man in the Yellow Hat and the Professor Wiseman (who he was working with) return...
Professor Wiseman: (observing the situation) Wha... wha... wha?
Man in the Yellow Hat: I'm learning sometimes it's better not to even ask.
When Betsy is trying to come up with a Christmas song in "A Very Monkey Christmas", Steve's ideas are hilarious.
Steve: (To the tune of "Deck The Halls") Hang things on the wall like holly, We got Christmas stuff hung on our walls!
Steve: (To the tune of "Good King Wenceslas") Oh, Aunt Margaret walked back home, carrying some cookies! I looked out of my window and, I said "Well, lookie-lookie!"
Betsy: But, that's not even about Christmas!
Steve: They're Christmas cookies!
Steve: (To the tune of "We Wish You A Merry Christmas") Do fish know when it is Christmas, do fish know when it is Christmas, do fish know when it is Christmas, or are they confused?
◊.The Man in the Yellow Hat: It seems the only word you can read is "BAD".
