Jim took a deep breath and inflated said balloon. FFFFOOOOOOFFFFF. "Control the size of Leonard Gondman and his clothes and footwear, please." he said. He let his grip on the balloon slip ever so slightly. A light hiss escaped.
Outside, Leonard Gondman felt himself shrink a few inches. And his clothes shrunk with him.
It was only a few inches of height lost, but Jim decided that he wanted to see how small Leno could get.
So without a second thought, he let out more air.
Leno shrunk, clothes and all, more smaller.
He was so surprised, he dropped the hosepipe he was holding. Immediately, he went and turned off the water.
Jim let out another small shot of air. Leno became smaller, now the same height as his patio table.
Leno couldn't understand what was happening to him. "Don't panic, Leno," he said to himself, "You're just hallucinating. The heat's just gettin' to you. Maybe I should go inside and cool down."
He headed for the back door, but he found that he couldn't reach the door handle. "What the-?!" Leno spluttered. "I can't reach the door handle anymore!"
Jim immediately let even more air out the balloon. Immediately, Leno shrunk right down to the size of a doll.
"Holy cow!" Leno exclaimed. "I've been shrunk!"
And yes, his clothes had shrunk with him.
