Pizza

Smith loved pizza. He would probably eat it for breakfast, lunch and dinner every day if he could.
The one he'd ordered for his Friday evening movie marathon was unrivalled though. It had every ingredient on the menu and they'd promised him some 'special surprises' too. He was quite excited. He spent hundreds of pounds every year in this particular pizzeria and they always looked after him well.
He waited expectantly, pacing up and down in his hall until the doorbell eventually rang.
He practically tore the door off its hinges.
"Hello, Mr Smith," the usual Friday delivery guy said with a smile.
"I can't wait for this!"
"You'll enjoy this one. Trust me." The driver winked as he walked away.
Smith sat down in his living room and opened the box. It smelt heavenly. The pizza was an explosion of colour and he grabbed a slice.
He could taste ham, salami, mushroom, peppers, prawns and...what was that? It was crunchy, but not in a good way.
He pulled the offending article from his mouth. It appeared to be a fingernail. Not a clipping, an actual whole nail.
Upon closer inspection he could see the outline of what looked like a finger on the next slice. Cheese was melted over the top, but there was no mistaking what it was.
Should he phone and complain?
Smith thought for a few seconds and then shrugged. He ate the entire piza.
