So I'm very late on the uptake and have just seen this image of the Big M (which is some sort of fantastic milkshake brand somewhere (more investigation leads me to believe it is in Oz)) which decided to make a Bacon flavoured version.
Instead they didn't. They just made the image and released it on April 1st.
Luckily I am slow on the uptake so have only seen this now!
But we surely can dream?
