The Continuum of Cartoon Fools (Dexter's Laboratory)

"The Continuum of Cartoon Fools" is the second half of the thirty-third episode in the second season of Dexter's Laboratory.

Plot
Dexter tries to figure out how Dee Dee keeps entering his lab every time he kicks her out and seals the entrance.

Why It's Anything But Foolish

 * 1) The title card pays great homage to the early Hanna-Barbera cartoons, Mh:besttvshows:Yogi Bear, Huckleberry Hound, Pixie & Dixie & Mr Jinks, Quick Draw McGraw, etc.'s flat and simplistic title cards with the "a Hanna-Barbera cartoon" label - which makes sense since this show's animation was still produced by that company when this episode released.
 * 2) Dexter writing on a test paper to see how he's distracted at the start was pretty funny and interesting.
 * 3) The ways Dexter got Dee Dee out of his lab were really clever as always. He first pushes Dee Dee out of the rug entrance, sends her to the mountain he was sent to with the yodelling man and smashes her copy of the transporter remote along with his, pushes her back into his secret refrigerator by arranging the word, "snacks" using some letter magnets and asks his computer to close a series of doors, tries sending her through the 2D facial filter and destroys it using the Discom Bobulator, etc.
 * 4) * It was also fun seeing Dexter figuring out how Dee Dee got into his laboratory by asking her if she got in using any of his different inventions.
 * 5) While Dee Dee is still annoying here, the episode does a hilarious job parodying the endless cycle of slapstick shenanigans & failures that occur within cartoons, and she at least finally stopped annoying Dexter when he locks his secret bookcase and swallows his key when finding out that was the reason why Dee Dee kept entering his lab over and over again.
 * 6) Though Dee Dee left Dexter alone as mentioned above, Dexter immediately regrets letting her out and feels instant remorse - saying that he's a fool and is no better than that stupid coyote or dumb duck (referencing both Wile E. Coyote & Daffy Duck from Looney Tunes) and calls himself the "continuum of cartoon fools".

The Only Bad Quality

 * 1) Dee Dee is still annoying and unbearable as usual for entering Dexter's lab over and over even after Dexter told her to get out as always until he locks his secret bookcase and swallows his key. She first enters the lab with a dynamite pack, then pushes a button on a transporter remote sending Dexter to a mountain where the Ricola Man yodels into an alphorn, along with foiling all of his other attempts.

Reception

 * It holds a rating of 7/10 on IMDB.

Trivia

 * This episode could explain how Dexter limited his entrances to his lab by getting rid of all the other possible ones. Thus, the later episodes just showed the bookcase entrance as the only one to the laboratory.
 * This is the only episode where a character (Dexter) is seen talking beside "the end" title card.
