I have been laughing at this for the last 5 minutes.
Was it intentional that you used the R in the sense that some non-Asian people use it to imitate the Asian accents?
Actually I struggled wih that. I thought someone may call me out for being racist or offensive, I couldn't think of another first name that rhymed with Jonny, although I guess I could have used Donnie but it wasn't as funny. I nearly didn't post the reply for fear of offending, I genuinely hope people found it funny and didn't get upset by it as I know exactly what you mean, I could hear myself saying it like you said.
Just a bit of harmless fun, when I read the comment it just popped into my head, I couldn't resist a reply.
