The Best Episodes Directed By Todd Grimes

An ancient cave cow comes to attack the barn animals! Meanwhile, scientists kidnap Otis, thinking he's really Cave Cow.

With Mr. Krupp gone and two terrible Melvins in charge, Harold and George fight back by hypnotizing their gym teacher, Mr. Meaner.

The boys use Melvin's new animal hybrid invention to make a creature that's a cross between a butt and a fly. But these butt-erflies are real monsters!

George and Harold trick Melvin into turning their bus into a time machine so they can reroute their field trip and see what ancient Rome was really like.

Harold and George can't wait to spend the summer together at camp. But not so fast, boys -- your old nemesis Mr. Krupp has a most unpleasant surprise.

The campers' splat-tastic game of paintball is rather rudely interrupted by a foul and formidable fiend known only as Camoflush.

George and Harold get revenge on their gym teacher by writing him into a ridiculous new comic. But the joke's on them when life imitates art.
