Wear your half-a-party-hat--(It’s just the rubber band).
Here’s your half-balloon--(It’s just a ribbon in your hand).
Blow out half the candles on your droopy half-a-cake--
(Half the flour, half the eggs, and half the time to bake).
Half of us will sing to you, but only half the song.
Half will sing your name correctly, half will sing it wrong.
Pour a half-a-glass of soda in your half-a-cup.
Open your half-presents--(empty boxes all wrapped up).
Play with half your friends, and when the party’s halfway through,
Make a good half-birthday wish, and may it half come true!
