As it's the Daisan holiday, sessions are not just A. and I at the moment - but her daughter, sister, niece, son, and, second cousin. We were working with animal names and we were getting confused between spiders and scorpions. someone mentioned Spiderman - and with a bit of superhuman note flicking I was able to give the K. for Spider-man; "kyobidza shawabu". Perhaps not so catchy, but everyone thought it was hilarious.
Score one for linguistics and one for laughs.
