No, it's not a joke, real penguins were rescruited to choose the famous jokes for the famous Penguin chocolate biscuit bars creating an all-round more authentic penguin experience for biscuit-lovers!
Over recent weeks McVitie’s and the keepers at Birdland in Bourton-on-the-Water have experimented with a number of ways to gauge the favourite jokes of the birds - including playing them over speakers and letting the penguins gravitate towards their favourite, or telling the penguins jokes "in person" to see which get the biggest, and most positive, reaction.
The testing is going very well, with the penguins showing a natural aptitude for choosing the funniest jokes due to their social personalities. Reactions have included interacting with the speakers, gathering around staff when they tell a particularly funny joke, lining up to listen to the jokes and clapping their wings…
Penguins are among the most social of all birds and communicate by vocalising and performing behaviour called "displays" – it’s believed that this behaviour is why the birds have been so receptive to the experiments so far. Staff at Birdland have reported that the most popular joke so far appears to be:
Q: How does a penguin build its house?
A: Igloos it together!
The jokes on McVitie’s Penguin chocolate biscuit bars will now be officially selected this way in future – with Birdland’s penguins now sole-ly responsible for the chocolately chuckle on pack.
