Cucumber Pie

Are cucumbers cool As a general rule? How fresh is a daisy? Are loons always crazy? How snug is a bug When he’s not in a rug? How gentle are lambs If not happy as clams? How clever’s a fox That’s as dumb as an ox? How fit is a fiddle Not clean as a whistle? Are doornails most dead, Or are dodos instead? Is it drier than toast To say “deaf as a post”? Such puzzles befuddle and much mystify Till suddenly you see they’re as easy as pie!
