Toilet

He had sat on the toilet so long that he couldn't feel his legs. This was why he should never take his phone with him.
It was starting to smell a bit in there and he decided a flush was in order.
He turned around and grabbed the handle on the cistern. He thrust it down.
A strange noise came from beneath him and he was sucked into the bowl and round the U-bend. He was carried through a series of pipes and into the sewer.
He still held his phone.
