I often say "brilliant" or "maaaaagnificent" when something goes wrong, I also insert "well" into the middle of a lot of my sentences and when I ask someone to show me something I almost always say "show us".

Also, has anyone else noticed how when you regularly see someone in passing you start out by saying "Hi" as you walk by, then the hi is no longer necessary and it becomes just a nod, then just a tilt of the head, then eventually a twitch of the lip is all you need to say hi.
