A little girl made a cup of tea for her mother.
"I didn't know you could make tea", said mum taking a sip.
"Yes, I boiled some water, added the tea leaves like you do, and then strained it into a cup. But I could't find the strainer, so I used the fly swatter."
"What!" exclaimed mum, choking on her tea.
"Oh, don't worry. I didn't use the new fly swatter. I used the old one."
