Any kid from the 90's can strike up a 2-hour long conversation about the best cartoons from those wonder years. Nickelodeon hosted some of the better ones, including Rugrats, Hey Arnold! and The Wild Thornberrys. No one can forget about some of those other animated pleasures from the 90's, such as Disney's Recess and the all-too hilarious South Park. One amazing artist named Isaiah Stephens put together some awesome drawings of these cartoon characters as grown up adults. If you've ever imagined how Tommy Pickles would look in his early 20's, then this gallery will amaze you. For even more awesome illustrations, head on over to Stephens' Tumblr profile page.
