Prime Baby

Thaddeus K. Fong can't understand why everybody is so crazy over his new baby sister, Maddie. His annoyance at her inability to say anything other than “ga” turns into amazement at the discovery that these “ga's” come in sets of prime numbers. The only logical explanation for this: she must be an alien.

Thaddeus' discovery is met with mockery, but he finds his proof when Maddie starts spitting up space pods holding small slug-like creatures, bent on world domination! Actually, they're missionaries of smiles and happy feelings, and Maddie's mouth is an inter-dimensional portal through which they travel. Imagine Thaddeus and Maddie's parents' concern when she starts spewing pods left and right. They bring in the government, and quarantine little Maddie for observation. Finally, Thaddeus is an only child again, and his parents are so distraught over their daughter's strange condition that they don't even notice the credit card bills he's racking up. Something's missing, though...

Very charming, very funny story about a boy's fantastic reality, dealing with a new sibling, and independence vs. loneliness. Presented as a three-panel comic strip series, the story works as a set of jokes cohered into a single storyline just as well as it does as a standalone graphic novel.
