Why?

Charly returned from his favorite yard sale with a new book called WHY? Charly's new book had answers to questions like: Why do dogs smell bad when they're wet? Which way do carousels turn? Why do firehouses have fire poles and Dalmatian dogs? Why do hot dog links come ten to a package and hot dog buns come eight to a package? How many colors are there in the rainbow, and what's the biggest spider in the world? The chicks used their new book to answer everyday why's?
