Mine is a lovely Guinness. Mmmm Guinness. Mmmmm. Lovely lovely Guinnessy goodness there. It's Guinness, I do like a good pint of Guinness.
I've always had a Guinness avatar every forum I visit. I like to keep my avatar roughly the same, that was my posts are easy to spot when I look back.
I made a 3D Guinness pint years ago, it has an animated variation too, where the drink settles all cool and slow like a proper Guinness like this, and a recently updated static one here. The one I use on this forum is a photo I found cos I was in a rush to get a Guinness avatar on here when I signed up.
