One of the stranger episodes...
29 January 2006 | by joncwriterSee all my reviews

"Dexter and Computress Get Mandark" is one of the stranger episodes of Dexter's Lab, in which the entire episode is narrated by a five year old boy (Tyler Samuel Lee) and animated in the style of a kid's crayon drawings. If I remember correctly the story revolves around a typical battle of wills and genius (or lack thereof) between Dexter and Mandark, and in true kid's improv form, it's narrated by way of "...and Dexter says..." or "...and Mandark says..." The plot goes out the window and things get sillier and sillier, somehow ending with Mandark's head expanding so much it explodes. There are many recurring jokes, including Dexter's great "You are stooopid, and another thing, you are stooopid, and don't forget, you are stoooopid!", Mandark's trademark "ha ha-ha! ha ha-ha!" laugh, and my favorite, "And Dexter says..." (with nothing following, leaving Dexter looking confused) that make this quirky episode memorable. As said, the episode doesn't really make too much sense, but it's hilarious nonetheless. Well worth looking for if you can find it.
