At the museum, George stumbles upon a closed Earth Science exhibit. Inspired, George decides to start his own rock collection and finds a great bunch of them in the park. Back at home, George accidentally cracks open a rock and is amazed to discover beautiful crystals inside! What else could George break open that might have a surprise? As George goes to work cracking open fruits and household items, Professors Wiseman, Pizza and Einstein realize that George's geode - and a trip to a special cave - might be exactly what the exhibit needs to be awesome again. / The Country Square Dance is tonight and George and The Man with the Yellow Hat are on their way to get their shoes shined. George spots a fun airplane chair through a storefront window and goes to investigate. It's a barber shop! The barber shows George some of his special techniques and George is amazed. He never realized how fascinating hair is! When the barber steps out, George steps in - and ends up giving Bill, Mr. Renkins, and The Man with the Yellow Hat unique hair styles memorable enough for the dance.
