Was returning back to my car after parking up to get a ticket from the machine in the muti storey and I noticed that the guy who had just parked up to my car was looking at the front of my car and I overheard him explaining to his young son that the bulge on the front of my bonnet was to help cool down the engine.
I smilied to myself and when I was out of earshot I said to my 3 year old, and told her its not used to help cool down the engine but in fact it is where the growl comes out from, she then turned around to me and said daddy dont be so stupid, its the scooby's mouth and thats how you feed it dinner every night
