We were doing a vocabulary quiz in class that involved me giving a clue and the kids working out the word I was thinking of.
"Louise and her mother were shopping in Liffey Valley. They wanted to go to the second floor and they took the moving stairs. What is the name of this?"
The boy whose turn it was thought long and hard. Then a big smile broke out on his face with sudden realisation.
"I know! It's an...ALLIGATOR!"
