Hiding Spider-Man on wedding cakes is apparently becoming a trend

After redditor PoliticalMilkman posted this photo of his cousin's wedding cake yesterday, both other redditors and Neatorama noted that this isn't the first time they've spotted Spider-Man hiding under a wedding cake. Is Spider-Man trying to slip away while the miniature groom is preoccupied? Or will they cut the cake only to find tiny Spider-Man bite marks inside? And why is it always Spider-Man hiding under the cake? Are other superheroes too proud to be caught sneaking beneath layers of fondant?

My cousin just got married, her cake had something a little different on it. [reddit via Neatorama]
