Australia has a lot of big things; like the big prawn, the big banana, the big pineapple etc.
I know what you mean, Canada has a big nickel, a big ... gee I can't remember the other things.
Here's a picture of something (that isn't normally) big. This photo was taken at one of the gardens in Suzhou, which is about an hours train ride from Shanghai.
Your photo is hilarious! I will definitely have to go hunting for something to match this. I have one idea in my neighbourhood. Stay tuned.
