Dexter's Laboratory #22

Mom's cheerful exclamation — "Oh, this is the best Mother's Day present EVER!" — tells you everything you need to know about what Dexter has cooked up this time: a potted flower with his own unmistakable blue-goggled scowl staring back at her from its petals. Cover artists Chris Savino and Bill Wray pack a ton of gentle comedy into that single moment, with Mom's wide-eyed delight playing perfectly against the plant's deeply unamused expression. If the story title "Mother's Day Monstrosity" is any indication, this June 2001 issue from DC's Cartoon Network line delivers exactly the kind of lab-gone-wrong charm the series does so well.
