Jim took a deep breath and inflated said balloon. FFFFOOOOOOFFFFF. "Control the size of Leonard Gondman and his clothes, 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, minus his footwear.
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. His shoes flopped up and down, like clown shoes, as He walks to the tap.
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 didn't get far till he tripped over his shoes. He stepped out of them, and shook his baggy socks off.
He ran, barefooted, to the door, but immediately 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 (apart from his shoes and socks) had shrunk with him.
Leno sat on the doorstep and wriggled his toes.
