Someone showed me this video a couple of years ago:
I thought it was hilarious!
It was brilliant marketing on the part of the Nolan company!
They use familiar & catchy tunes that people will hum, sing along to and remember. They throw in an adorable mouse, a dash of comedy and a hint of drama, thus creating an advertisement that you’ll kinda’ enjoy (admit it!) and want to see over again (you pressed ‘replay,‘ didn’t you?).
They do another one with a squirrel and nuts that I found when looking for this one, but I didn’t think it was as good.
