I'm looking over a four-leaf clover and a poppy on the cliffs of Dover.

A tetrahedron has four faces. In baseball there are four bases.

Violin and cello have four strings and a honeybee has four wings.

Four legs in a table and chair. Four elements:   water, earth, fire, air.

Four croquet balls—   red, blue, yellow, & black. Four elephants support Earth   on a tortoise's back.

Four chambers pumping   blood in your heart. Four Seasons you'll find   in music and art.

Every square has four sides. Let the Four Books be your guides.

Four bases in spiral DNA. Wishing you a   Happy 4th Birthday!
