Panel 1: We start out with Deanna poking the snow with a stick; this gives Mike, who's standing behind a snow-covered pine tree, a wonderful, awful idea because he still has deviltry on his mind.
Panel 2: As she wonders why she was made to yo-yo from Burlington back to Milborough, Mike builds the Snowball of Ultimate Doom..
Panel 3: As he lines up his shot, she bends the tree back.....
Panel 4: ....and releases it with a mighty WHAAAAAANNNNNG, thereby pelting the stupid little tool who will one day remind us how little he thinks of her by rushing into a fire to save a laptop, the stupid bastard.
Panel 5: As he stands there covered in snow, he tells Lawrence "Girls are smarter than they look!"
Summary: She's not THAT smart, kiddo; after all, she'll eventually marry you, wear her hair like a Romulan and give up a lucrative career as a pharmacist to open up a money-hemorrhaging sewing school.
