That one says "Howay the lads!"

 

If you've got a smartphone you can use a barcode scanner app, point the camera at it and read the contents, they're often used to share urls on adverts or stickers or whatever.

Aye. Always considered using them for one of my websitey projects, but then I realise how freaking pointless they are.
