"Yep, ok, let's hear it. Psy always has good riddles." Isaac said, rubbing his hands together.
"Ok, you're locked in a room. In the middle of the room is a pipe, half-cemented into the floor. The pipe is only wide enough to fit a ping pong ball. And there just so happens to be one at the bottom of the pipe. How convenient. You are only allowed out of the room if you can get the ping pong ball out of the pipe. You have a mirror, a ruler, a paper clip, a piece of string and a magnet. How do you get the ping pong ball out?"
Silence.
"Hmm..." Taylor said frowning. "Umm, you tie the paper clip to the ruler, unfold the paper clip a bit so you can poke a hole into the ping pong ball and pull it out like that?"
"No."
"Umm, you... umm, no that won't work..." Isaac muttered.
"Do you need all the items?" Rita asked presently.
"No."
"Do you need the paper clip?" Taylor asked immediately.
"No."
"The ruler?" Isaac asked.
"No."
"The string?" Taylor asked.
"No."
"The magnet?"
"No."
"The mirror?" Isaac asked.
"Umm," Babsie paused to think, "it may be useful if you're female."
"Useful if you're female?" Isaac repeated. "Hmm..."
They all stopped and thought for a moment.
"Eww." Rita said suddenly. "I know how."
"How?" Taylor asked.
"Yeah Rita?" Babsie asked gleefully. "How?"
"Well, uhh, ping pong balls float don't they?"
"Yep."
"So you ahh," Rita looked a little embarrassed, "you urinate down the pipe."
Taylor and Isaac laughed.
"Yep!" Babsie grinned triumphantly. "That's it!"
