So, I’m thinking it’s not just me… there are countless times when my pronunciation mistakes have ended up sounding like something completely ridiculous in English and I can’t find any threads dedicated to this, so here goes!

I also believe that connecting imagery to what you’re learning is great, especially when it is funny or moving in some way.
Here’s my most recent example from a few minutes ago that prompted me to start this post today:
