|Series(s)||Old Series 5|
|Card Number(s)||172a / 172b|
NAT Nerd or CLARK Can't is card number 172a/172b in the original fifth series.
 The card shows a nerdy boy wearing a shabby, stained and ill-fitting superhero costume with "GPK" emblazoned on his chest. He's carrying some comics and has a box filled with more comics at his feet.
The card makes fun of how "nerdy" types often collect comic books and how little boys like to play at being superheroes. Also, the b name is a parody of Clark Kent, the alter ego of the comic book superhero Superman.
Nat Nerd was one of the seven main Garbage Pail Kids in The Garbage Pail Kids Movie. He often wets his pants. He and the other six kids were captured by the State Home for the Ugly when they were looking for their friends, the other Garbage Pail Kids. Dodger and Captain Manzini were able to rescue the seven kids along with everyone else incarcerated at the Home for the Ugly, but were too late to rescue the other Garbage Pail Kids. Nat Nerd was played by Larry Green and voiced by Jim Cummings.
Nat Nerd also made several cameo appearances in the Garbage Pail Kids Animated Series. He was even the main character in the movie parody Supernerd, a parody of the 1978 Superman movie.
