Pretty much mate, especially the glazed cross-eyed look. I'm just in the process of emptying my Mum's fridge of all alcoholic content. I'm on my 6th can since I got in from work this avvy!!!!
So Jonny you're no ordinary Caveman, you're an Alcoholic Caveman living in the 21st Century. (What a great show this would be, I would be a millionare)
Nice new sig by the way.
You might want to consider using something called body spray or deodarant(or both) because you wouldn't want people from passing out after you walk by, afterall you do live in a cave and have been frozen for the past millions of years.
