Rock Pig
I was given the fridge magnet pictured on this page by a very good friend a few years ago, and was slightly surprised, and underwhelmed at the time, as I am sure my face gave away...
But now I am putting out pig-related geocaches, it has been a great source of inspiration.
This is a tune off 'Era Vulgaris', which is sadly probably my least favourite album from the band Queens of the Stone Age (QoTSA). But that is probably because all the rest are absolutely amazing and should be listened to by everyone.
Although I love these songs, I am over 18, and rock isn't always for children, so if you seek out this music (which I heartily recommend you do), here is my parental advisory sticker:
