A day at the zoo

One of my best mates proposed with his head in one. Amy Winehouse reportedly put her head, beehive and all, through one (damn I wish I had a photo). What am I talking about? Well unfortunately I don't know what you'd call them except 'those seaside thingies that you put your head through' - there are quite a few of them round Bristol Zoo at the moment and it was me what dunnum. Here's the most recent one, snapped today. They seem pretty popular, but as you can see some like them more than others..
