Baboon tries to impress Loulabelle twice in this episode and accidentally puts on Weasel's old diaper twice when they are in nursery and at the retirement home.
TONS of guest appearances in this episode: Cow & Chicken, Dexter, Quick Draw McGraw, Johnny Quest (The Original!), Betty Rubble, Pebbles & Bamm-Bamm, Boo-Boo Bear, Mr. Slate and Ranger Smith (I probably missed a couple).
I.R. Baboon: I.R. cartoon star. I.R. be big! It cartoons that got small.
Baboon's line about him still being a big star is a spoof of the line "I am big--it's the pictures that got small!" said by the character of Norma Desmond (played by Gloria Swanson (March 27, 1899 – April 4, 1983)) in the 1950 movie Sunset Boulevard, directed by Billy Wilder.
The movie was nominated for eleven Academy Awards and won three. In 1998, it was ranked number twelve on the American Film Institute's list of the 100 best American films of the 20th century, and in 2007 it was 16th on their 10th Anniversary list.
The same line would later be spoofed again in another one of Cartoon Network's original series, Chowder, in the episode "Big Food".
