Here’s a question for some smart fellow.
Why are tennis balls always yellow?
I’ve never seen one green or blue!
Have you . . . or you . . . or even you?
There are other colors that they could be,
like red or purple, don’t you agree?
Maybe we should take a vote
and then promote . . .
a multicolored tennis ball . . .
for all!
