Perhaps Pacers can be given a new nickname: "Tiggers"
The wonderful thing about Tiggers
Are Tiggers are wonderful things
Their tops are made out of rubber
Their bottoms are made out of springs
They're bouncy, trouncy, flouncy, pouncy
Fun, fun, fun, fun, FUN!
But the most wonderful thing about Tiggers
Is there's more than only one. (slight edit!)
