1. Spongebob Squarepants
(source)
Yellow. Adorable. Bubbly. Sure, he is all these things, but, with a second glance, it becomes apparent who Mr. Squarepants really is. Because he has had a full-time job for almost twelve years, he is at least thirty. So, he’s a thirty-year-old man who lives all alone with his pet snail, has a best friend with the brains of a rock, and spends most of his time catching bubbles and bothering his neighbor. Basically, he’s a psychopath.
