I’m technically on vacation this week, so I’ll keep this quick then get back to doing nothing.

There are four members of my family. Frequently, we each go about entertaining ourselves because if three of us agree to an activity there is an unwritten rule that the fourth will not. Sometimes, however, the family-quality-time elves visit, like they did last night.

We were playing Trivial Pursuit and my son got this question: what are the two plural forms of the word “platypus”?

He turned to me with a puzzled look, hoping I’d help him out. “Well,” I said, “think of some other words that end with ‘-us’ and how their plurals are formed.”

“So…maybe ‘platypi’?” he asked.

“Sure,” said his dad, “and ‘platipussies’.”
