Hopefully I'm not alone in this, but there are times when I'm not sure my brain is switched on at all.
Just now I was wondering if there might be an update on the shipping of a shiny new Count To Five, I then thought about checking online what time it is in Canada, but then hesitated as I wouldn't know which bit of Canada to look up.
The thought that inspired this post was "They're called Montreal Assembly, so you might be able to guess where they're based, you idiot."
Which reminded me of a time I went to a friend's birthday do in a pub far enough away for me to have to drive, so I wasn't drinking (otherwise that might have been an excuse). I was standing at the bar, a few feet from my friend trying to remember how much older than him I was (can't remember why).
After a minute or two I thought to myself "Well, you know how old you are, and he's wearing a large badge with flashing LEDs and a big "40" written on it, so you could probably work it out . . . you idiot".
