Does anyone old enough remember "bubble gum, bubble gum in a dish" or "eeny, meeny, miny, moe"? Children use such rhymes to choose teammates for some activity or game. Here is another:

"Ching, Ching China sitting on a fence [or bench] trying to make a dollar out of fifteen cents. She miss, she miss, she miss like this!"

The cheaters attempt to make up the difference and add more to the tallies in a plausible manner to claim victory for their candidates. The cheaters are trying to "make a dollar out of fifteen cents."
